REACTION OF TERTIARY PHOSPHINE DICHLORIDES WITH THIOLS IN THE PRESENCE OF TRIETHYLAMINE. A CONVENIENT METHOD FOR THE REDUCTION OF PHOSPHINE OXIDES TO PHOSPHINES

Abstract The reaction of phosphine dichlorides with 1- or 2-alkanethiols or benzenethiol in the presence of triethylamine and subsequent distillation afforded phosphines and disulfides in good yields. The reaction was shown to be useful for reduction of tertiary phosphine oxides to the corresponding phosphines.
