Bodroux, F. published the artcileTransformation of Esters of α-Bromaliphatic Acids into the Corresponding α-Iodine Derivatives, Safety of Ethyl 2-Iodopropionate, the publication is Compt. rend. (1907), 1216-17, database is CAplus.

Ethyl α-chloracetate reacts with magnesium iodide giving ethyl iodacetate (Ibid, 140, 1597). The authors find that the α-brom substituted esters react in a smooth manner with magnesium iodide in ether giving the iodine derivatives. Experimental: Ethyl iodacetate, ICH₂.CO₂C₂H₄. b₂₄ 85-86°; d₂₄ 1.762. Ethyl α-iodpropionate, CH₂.CHI.CO₂C₂H₄, b₂₄ 85°, d₁₇ 1.662. Ethyl α-iodbutyrate, C₂H₅CHI.CO₂C₂H₄, b₂₁ 100-101°; d₁₇ 1.570. The iodine-substituted esters are unstable and decompose under influence of light and heat with liberation of iodine. They volatilize at ordinary temperature

Compt. rend. published new progress about 31253-08-4. 31253-08-4 belongs to iodides-buliding-blocks, auxiliary class Iodide,Ester, name is Ethyl 2-Iodopropionate, and the molecular formula is C5H9IO2, Safety of Ethyl 2-Iodopropionate.

Bojarska-Dahlig, Halina published the artcileFeasibility of synthesizing 3,5-diiodo-4-pyridoxyacetic acid, the isomer of 3,5-diiodo-4-pyridone-N-acetic acid, Quality Control of 101-29-1, the publication is Acta Poloniae Pharmaceutica (1957), 457-8, database is CAplus.

The Ag salt of 3,5-diiodo-4-hydroxypyridine and ClCH₂CO₂Et in xylene or C₅H₅N give Et 3,5-diiodo-4-pyridone-N-acetate (I), m. 178-9°. The O-substituted isomer is not formed. The identity of I was established by determination of the mixed m.p. of I and of the free acid from I (m. 241-2°) with pure compounds prepared by a different method.

Acta Poloniae Pharmaceutica published new progress about 101-29-1. 101-29-1 belongs to iodides-buliding-blocks, auxiliary class Pyridine,Iodide,Carboxylic acid,Ketone, name is 2-(3,5-Diiodo-4-oxopyridin-1(4H)-yl)acetic acid, and the molecular formula is C7H5I2NO3, Quality Control of 101-29-1.

Mostad, Asbj published the artcilePyridine-iodomonochloride. Charge transfer complex studied by ESCA [electron spectroscopy for chemical analysis], COA of Formula: C5H5ClIN, the publication is Chemical Physics Letters (1973), 23(2), 157-9, database is CAplus.

The charge transfer complex pyridine-ICl and its dissociation components were studied at equilibrium in the gas phase by means of ESCA. At. core energy shifts in the complex relative to its components are: N 1s: +0.9 eV, I 3d: -0.8 eV, Cl 2p: <0.3 eV. If the potential model is used, these shifts suggest a transfer of 0.1 electrons from the N to the I atom in the complex.

Chemical Physics Letters published new progress about 6443-90-9. 6443-90-9 belongs to iodides-buliding-blocks, auxiliary class Pyridines, name is Pyridine Iodochloride complex, and the molecular formula is C5H5ClIN, COA of Formula: C5H5ClIN.
