Abstract
Phosphinic acid chlorides are converted directly into phosphinous acid-boranes in a process utilizing BH3·THF complex as a reducing agent. The process is general and affords phosphinous acid-boranes in good to very high yields. Phosphinous acid-boranes have been found to react readily with alkylating, acylating, reducing, halogenating and deborating agents to produce the corresponding phosphinous acid-borane esters, phosphinous acid-borane anhydrides, sec-phosphine oxides, sec-phosphine boranes and phosphinic acid halides, respectively. The efficient procedures for these conversions have been developed and their scope has been outlined.
