Abstract

The reaction of diiodomethane and triethylaluminum with substituted 1-alkenylaluminums obtained by the Zr-catalyzed carbo- or cycloalumination of mono- or dialkyl-substituted alkynes resulted in the selective formation of di- and tetrasubstituted cyclopropanes. 1-Alkenylaluminums prepared from substituted propargylamines reacted with diiodomethane and triethylaluminum to give substituted allylamines. A plausible mechanism for the reaction of the 1-alkenylaluminums with diiodomethane/triethylaluminum is proposed.
