Abstract
Arylmethylenecyclopropanes 1 can react with 3-methoxy-1,3,3-triarylprop-1-yne 2 or 1,1,3-triarylprop-2-yn-1-ol 2-OH to give the corresponding functionalized methylenecyclobutene, cyclobutane, and cyclopropane derivatives in the presence of Lewis acid BF3 center dot OEt2 under mild conditions. A plausible Meyer-Schuster rearrangement mechanism has been proposed.
