Preparation et etude de nouveaux derives organozinciques allyliques fonctionnels

Lambert, Francois,Kirschleger, Bernard,Villieras, Jean

, p. 273 - 286 (2007/10/02)

Stable organozinc compounds derived from alkyl-3-alkyl-2-(bromomethyl)-propenoates have been prepared.NMR 13C, 1H and IR studies show only one Z stereoisomer (no methylenic form) with a strong chelation between zinc and the carbonyl oxygen of the ester and solvated by only one solvent molecule.Hydrolysis can be achieved by two concurrent mechanisms with or without transposition.
