Tahmouresilerd, Babak published the artcileMake room for iodine: systematic pore tuning of multivariate metal-organic frameworks for the catalytic oxidation of hydroquinones using hypervalent iodine, Recommanded Product: Dimethyl 2-iodoterephthalate, the publication is Catalysis Science & Technology (2018), 8(17), 4349-4357, database is CAplus.

Iodine sites have been incorporated in both MIL-53 (Al) and UiO-66 (Zr) MOFs. A multivariate approach was used to increase the accessible area within the pores to allow for the catalytic oxidation of a model substrate, hydroquinone, to the corresponding quinone. In the process, three new phases of MIL-53 were discovered, one of which proved instrumental in allowing catalysis to occur. Both UiO-66 and MIL-53 with 25% incorporated iodine containing linkers allowed for a near-ideal balance between high d. of catalytic sites and sufficient space for mass transport to enable catalysis to occur. Good conversions and selectivities were observed in nitromethane, Et acetate, acetone and ethanol with UiO-66 which proved to be the more active of the two catalysts. Oxone and 3-chloroperbenzoic acid acted as competent cooxidants. XPS revealed that the reaction proceeded through an I(III) oxidation state. The MIL-53 framework was readily recycled while the UiO-66 MOF suffered from catalyst deactivation due to particle agglomeration. UiO-66 with 25% iodine containing linker proved to be a competent catalyst for a variety of substituted hydroquinones.

A variety of substituted isocoumarins, e.g. I [R¹ = H, MeO; R² = H, MeO, MeO₂C; R³ = HO(CH₂)₃, Ph, n-hexyl, etc.; R⁴ = H, iodo, 4-O₂NC₆H₄S, PhSe], and α-pyrones, e.g. II [R⁵ = H, Me, Ph; R⁶ = H, Ph; R⁵R⁶ = (CH₂)₃; R⁷ = Bu, Ph], are readily prepared in excellent yields under very mild reaction conditions by the reaction of o-(1-alkynyl)benzoates, e.g. III (R⁸ = Me, Me₃C), or (Z)-2-alken-4-ynoates, e.g. IV (R⁹ = Me, Et), resp., with ICl, I₂, PhSeCl, p-O₂NC₆H₄SCl, and hydrogen iodide. This methodol. accommodates various alkynyl esters and has been successfully extended to the synthesis of polycyclic aromatic and biaryl compounds

Al-Amin, Mohammad published the artcileSelectivity, Compatibility, Downstream Functionalization, and Silver Effect in the Gold and Palladium Dual-Catalytic Synthesis of Lactones, Product Details of C10H9IO4, the publication is Organometallics (2014), 33(19), 5448-5456, database is CAplus and MEDLINE.

The chemo- and regioselectivity and functional group compatibility in Au and Pd cooperatively catalyzed cross-coupling reactions were determined in the synthesis of lactones; the selectivity in the Au and Pd dual-metal catalysis system was distinct from that available for the same class of substrates in systems with only Au catalysis or only Pd catalysis rather than dual catalysis. The dual-catalytic rearrangement reaction selectively promoted oxidative addition at the C-O bond over the C-Br bond, providing a useful C-Br bond handle for downstream functionalization showcased via Suzuki-Miyaura and Sonogashira coupling reactions. Product classes were expanded from isocoumarins to three previously unpublished ring classes: pyrone, indolepyrone, and furopyrone.

Duhamel, Jean published the artcileStudy of Energy Migration and Trapping in a Poly(ethylene 2,6-naphthalenedicarboxylate) Matrix by Fluorescence Spectroscopy, Quality Control of 165534-79-2, the publication is Macromolecules (2000), 33(17), 6344-6352, database is CAplus.

The efficiency of di-Me iodoterephthalate (I-DMT), 2,6-di-Me 1-benzoylnaphthalate (BZN), and 2,6-bis(2-hydroxyethylthio)naphthalene (NSEG) at quenching the fluorescence of the poly(ethylene 2,6-naphthalenedicarboxylate) (PEN) matrix has been investigated by steady-state and time-resolved fluorescence spectroscopy. All three quenchers are capable of capturing the energy migrating between naphthalene dimers. Steady-state fluorescence data indicate that, after the quencher has trapped the migrating energy, the excited quencher can relax either via nonradiative processes (I-DMT) or via radiative processes (BZN and NSEG). Fluorescence decay measurements show that NSEG quenches PEN fluorescence best, followed by BZN, and I-DMT is the worst quencher. Quenching efficiency of a given quencher increases linearly with quencher concentration, for quencher contents below the overlap concentration, for which the entire polymer matrix is covered by quenchers. Above the overlap concentration, quenching efficiency increases at a slower pace because any addnl. quencher quenches an already quenched volume Our exptl. results could be interpreted by compartmentalizing the quenching process in the polymer matrix. Compartmentalization could be handled by a blob model, which was applied to quantify the quenching efficiency of I-DMT and BZN.
