Abstract

Scheme I invariably results in contamination by starting material while the second route makes use of less easily accessible dichlorophosphine~.~ A far more convenient procedure is reported here for the preparation of these compounds. On hydrolysis with water, chloroaluminate (Kinnear-Perren) complexes4 break up to yield alkylphosphonic dichlorides. Substitution of hydrogen sulfide in place of water, however, results in several ...
