Abstract
L'invention concerne un procédé de préparation d'un diméthylformylcyclopropane à substituant dihalogénovinyle. Le procédé consiste à faire réagir avec un tétrahalogénométhane le 3,3-diméthylpent-4-én-1-al ou son acétal formé avec un alcool aliphatique inférieur ou un alkylène-diol en présence d'un initiateur de radicaux libres puis à faire réagir le composé obtenu avec au moins 2 équivalents d'une base. Les composés obtenus par le procédé de l'invention sont des composés chimiques intermédiaires intéressants à utiliser dans la production d'insecticides.
