Abstract

A convenient method of wide scope for the synthesis of the rare tetrahydroisophosphinolinium and tetrahydrophosphinolinium salts has been developed from readily available starting materials. Treatment of a variety of tertiary phosphines (all containing an aryl group and/or an arylmethyl group) with allylic type halides gave phosphonium salts containing a B-alkenyl substitutent. Cyclization of these salts occurred ...
