Abstract
Ce sont des 3,3-diméthyl-4-(2,2-dihalogénovinyl)-4-butanolides de formule II. Ces butanolides sont des composés de départ intéressants pour la préparation d'esters d'acides 3,3-diméthyl-4,6,6-trihalogéno-5-héxenoïques de formule V, consistant à faire réagir lesdits butanolides II avec un alcool de formule III en présence d'un acide halogénhydrique de formule IV ou d'un réactif halogénant. Les dérivés V, par réaction avec une base forte, conduisent à des esters d'acides 2,2-diméthyl-3-(2,2-dihalogénovinyl)-cyclopropane-carboxylique I qui sont des produits intermédiaires intéressants pour la synthese de la partie acide d'insecticides du type pyréthrine.
