Procedure to prepare in all possible forms of isomers or as mixtures of isomers, esters from acids 2,2-dimethyl cyclopropane carboxylic - and - biaryl alcohols

摘要

Process for the production of Esters of acids 2,2-dimethyl cyclopropane carboxylic - and - isomers of biaryl alcohols, and mixtures of isomers of formula (i), in which W, X, y, Z, R and R1 - R4 may be several radicales.consiste in the reaction of an Acid of formula (ii) with an alcohol d And the formula (iii), in which all symbols have the same meaning as in formula (i).The reaction is carried out in the presence of a base terciaria.estos compounds have applications for the preparation of Pesticides against the Parasi compositions
