Page/Page column 16-17, (2016/05/19)
The present invention relates to the field of perfumery. More particularly, it concerns co-polymeric latex particles derived from 2-oxo-2-(3- or 4-vinylphenyl)acetates capable of liberating an active molecule such as, for example, an aldehyde or ketone up

Page/Page column, (2014/09/30)
The present invention relates to the field of perfumery. More particularly, it concerns co-polymeric latex particles derived from 2-oxo-2-(3- or 4-vinylphenyl)acetates capable of liberating an active molecule such as, for example, an aldehyde or ketone upon exposure to light. The present invention concerns also the use of said latex in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's latex.
Radical Decarboxylative Alkylation onto Heteroaromatic Bases with Trivalent Iodine Compounds

Heteroaromatic bases containing nitrogen atoms were easily alkylated with carboxylic acids in the presence of benzene and pentafluorobenzene via radical pathways.Similarly, the alkylation onto heteroaromatic bases was carried out with oxalic acid monoalkyl esters, which were prepared from alcohols and oxalyl dichloride, in the presence of the same trivalent iodine compounds.Moreover, this system was applied to the synthesis of C-nucleosides with the carboxylic acids bearing a sugar moiety.
FACILE RADICAL DECARBOXYLATIVE ALKYLATION OF HETEROAROMATIC BASES USING CARBOXYLIC ACIDS AND TRIVALENT IODINE COMPOUNDS

, p. 6559 - 6562 (2007/10/02)
Many kinds of heteroaromatic bases were easily alkylated by the reaction of carboxylic acids with benzene or pentafluorobenzene via radical decarboxylative pathways.This system was further applied to the reaction with tetrahydrofurylcarboxylic acid, 1-(2,3,5-tri-O-benzyl)-D-ribofuranosylacetic acid, and 1-(2,3,5-tri-O-benzyl)-D-ribofuranosylcarboxylic acid for the model synthesis of C-nucleosides.
Alkylation of Aromatic Heterocycles with Oxalic Acid Monoalkyl Esters in the Presence of Trivalent Iodine Compounds

Aromatic heterocycles containing nitrogen atoms were easily alkylated with the half esters of oxalic acid, which were prepared from alcohols, in the presence of benzene via radical decarboxylative pathways.This is the first method for the alkylation of aromatic heterocycles with alcohols via the formation of half esters of oxalic acid.
