Efficient Copper-Catalyzed Trifluoromethylation of Aromatic and Heteroaromatic Iodides: The Beneficial Anchoring Effect of Borates was written by Gonda, Zsombor;Kovacs, Szabolcs;Weber, Csaba;Gati, Tamas;Meszaros, Attila;Kotschy, Andras;Novak, Zoltan. And the article was included in Organic Letters in 2014.Electric Literature of C6H4INO2 This article mentions the following:

Efficient copper-catalyzed trifluoromethylation of aromatic iodides was achieved with TMSCF₃ in the presence of tri-Me borate. The Lewis acid was used to anchor the in situ generated trifluoromethyl anion and suppress its rapid decomposition Broad applicability of the new trifluoromethylating reaction was demonstrated in the functionalization of different aromatic and heteroaromatic iodides. In the experiment, the researchers used many compounds, for example, 2-Iodopyridine-4-carboxylic acid (cas: 58481-10-0Electric Literature of C6H4INO2).

2-Iodopyridine-4-carboxylic acid (cas: 58481-10-0) belongs to iodide derivatives. Iodide-containing intermediates are common in organic synthesis, because of the easy formation and cleavage of the C–I bond. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I. This periodic order also follows the atomic radius of halogens and the length of the carbon-halogen bond.Electric Literature of C6H4INO2

Nickel-Catalyzed Cross-Coupling between Functionalized Primary or Secondary Alkylzinc Halides and Primary Alkyl Halides was written by Jensen, Anne Eeg;Knochel, Paul. And the article was included in Journal of Organic Chemistry in 2002.COA of Formula: C4H8ClI This article mentions the following:

In the presence of Bu₄NI (3 equiv) and 4-fluorostyrene (20 mol %), unreactive primary and secondary alkylzinc iodides undergo nickel-catalyzed cross-couplings with various primary alkyl iodides or bromides. More reactive secondary dialkylzincs and the mixed zinc organometallics RZnTMSM undergo the cross-coupling reaction in the absence of Bu₄NI. The bicyclic secondary diorganozinc prepared via boron-zinc exchange reacts with high retention of configuration. Free NH-groups are tolerated in the cross-coupling allowing the synthesis of aminated products. In the experiment, the researchers used many compounds, for example, 1-Chloro-4-iodobutane (cas: 10297-05-9COA of Formula: C4H8ClI).

1-Chloro-4-iodobutane (cas: 10297-05-9) belongs to iodide derivatives. Iodide-containing intermediates are common in organic synthesis, because of the easy formation and cleavage of the C–I bond. Organoiodine lubricants can be used with titanium, stainless steels, and other metals which tend to seize up with conventional lubricants: organoiodine lubricants can be used in turbines and spacecraft, and as a cutting oil in machining.COA of Formula: C4H8ClI

And the article was included in Bioorganic & Medicinal Chemistry Letters in 2012.Category: iodides-buliding-blocks This article mentions the following:

Presented here are initial structure-activity relationship (SAR) studies on a series of novel heteroaryl fused tetracyclic indole-based inhibitors of the hepatitis C viral polymerase, NS5B. The introduction of alternative heterocyclic moieties into the indolo-fused inhibitor class significantly expands the reported SAR and resulted in the identification of pyridino analogs, typified by compounds I and II that displayed excellent potency against the NS5B polymerase of both HCV 1a and HCV 1b genotypes. In the experiment, the researchers used many compounds, for example, 4,5-Diiodo-1H-imidazole (cas: 15813-09-9Category: iodides-buliding-blocks).

4,5-Diiodo-1H-imidazole (cas: 15813-09-9) belongs to iodide derivatives. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.Category: iodides-buliding-blocks

New phenoxyacetic acid antagonists of CRTH2 are described. Following the discovery of a hit compound, I, by a focused screening, high protein binding was identified as its main weakness. Optimization aimed at reducing serum protein binding led to the identification of several compounds that showed not only excellent affinities for the receptor (41 compounds with K_i < 10 nM) but also excellent potencies in a human whole blood assay (IC₅₀ < 100 nM; PGD2-induced eosinophil shape change). Addnl. optimization of the pharmacokinetic characteristics led to the identification of several compounds suitable for in vivo testing. Of these, II (R¹ = n-Pr, R² = Me; R¹ = n-Pr, R² = F) were tested in two different pharmacol. models (acute FITC-mediated contact hypersensitivity and ovalbumin-induced eosinophilia models) and found to be active after oral dosing (10 and 30 mg/kg).

The synthesis of a new benzocyclobutene based polymer, PSBBB, designed as a dielec. material for use in organic thin film transistors was reported. Compared to conventional benzocyclobutene-based materials, the introduction of a butoxide substituent at the 7-position of the benzocyclobutene pendant unit on the polymer allowed PSBBB to be cross-linked at temperatures of 120°, thus rendering it compatible with the processing requirements of flexible plastic substrates. The crosslinking behavior of PSBBB was studied by FTIR spectroscopy and DSC, demonstrating crosslinking of the polymer after curing at 120°. Bottom-gate bottom-contact organic thin film transistors were fabricated using PSBBB as dielec., affording a performance comparable to that of other dielec. polymeric materials. In the experiment, the researchers used many compounds, for example, 4-Bromo-2-iodophenol (cas: 207115-22-8Electric Literature of C6H4BrIO).

4-Bromo-2-iodophenol (cas: 207115-22-8) belongs to iodide derivatives. Organoiodine compounds occur widely in organic chemistry, but are relatively rare in nature.

Synthesis of 2′-Substituted 4-Bromo-2,4′-bithiazoles by Regioselective Cross-Coupling Reactions was written by Bach, Thorsten;Heuser, Stefan. And the article was included in Journal of Organic Chemistry in 2002.Reference of 10297-05-9 This article mentions the following:

The synthesis of the title compounds [I; R = Bu, CH₂CHMe₂, CH₂CH₂Ph, (CH₂)₄Cl, CHMe₂, sec-Bu, Ph, CCCMe₃, CCPh, etc.] was achieved in two steps starting from readily available 2,4-dibromothiazole (II). In a regioselective Pd(0)-catalyzed cross-coupling step, II was converted to a variety of 2-substituted 4-bromothiazoles (III, same R) (10 examples, 65-85% yield). Alkyl and aryl zinc halides were employed as nucleophiles to introduce an alkyl or aryl substituent. The Sonogashira protocol was followed to achieve an alkynyl-debromination. Bromo-lithium exchange at C-4 and subsequent transmetalation to zinc or tin converted the 4-bromothiazoles to carbon nucleophiles, which underwent a second regioselective cross-coupling with another equivalent of 2,4-dibromothiazole. The Negishi cross-coupling gave high yields of the 2′-alkyl-4-bromo-2,4′-bithiazoles (88-97%). The synthesis of the 2′-phenyl- and 2′-alkynyl-4-bromo-2,4′-bithiazoles required a Stille cross-coupling that did not proceed as smoothly as the Negishi cross-coupling (58-62% yield). The title compounds, which were accessible in total yields of 38-82%, are versatile building blocks for the synthesis of 2,4′-bithiazoles. In the experiment, the researchers used many compounds, for example, 1-Chloro-4-iodobutane (cas: 10297-05-9Reference of 10297-05-9).

1-Chloro-4-iodobutane (cas: 10297-05-9) belongs to iodide derivatives. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I.Reference of 10297-05-9
