Abstract

Some phospholene oxides were transformed into the corresponding phosphine-boranes. The reaction of a 2-phospholene-borane with dichlorocarbene gave the phospholene- and the phospholane-dichloromethyl-boranes as the major products, and the cyclopropane derivative as the minor component. A similar reaction of 3-phospholene-boranes afforded only the phopholene-and the phospholane-dichloromethyl-boranes. A phosphabicyclohexane-borane was synthesized from the P-oxide by change in the functionality. The dihydrophosphinine-boranes were prepared by cyclopropane ring opening of a phosphabicyclohexane, or by change in the functionality of the dihydrophosphinine oxides. The reaction of dihydrophosphinine-boranes with dichlorocarbene did not result in the formation of the desired phosphepine. This species was eventually synthesized by change in the functionality of the P-oxide. The preparation of unsaturated phosphine-boranes was usually complicated by reduction side-reactions.
