Abstract

Résumé The reaction of an alkylidenecyclopropane of type 1, bearing an Internal nucleophile (β-diester, β-keto-ester, β-sulfonyl-ester, amine) with lodobenzene in the presence of catalytic amounts of a palladium (o) complex leads to cyclic compounds 3 and (or) 4 depending on the number of carbon atoms between the nucleophilic moeity and the double bond. These compounds result from the intramolecular attack of a II-allyl-palladium ...
