- Abstract
Bis-chloromethyl-phosphinates, -thiophophinates, and -phosphinic amides are formed in fair yield by treating either bis-chloromethyl-phosphinic or-thiophosphinic chloride with alcohols, thiols, or amines in the presence of equivalent amounts of acid binding agents. Unexpectedly, the thiophosphinates show no insecticidal activity and only the β-cumaryl derivative exhibits a low herbicidal activity. Reduction of bis-chloromethyl-thiophosphinic chloride to bis-chloromethyl-phosphinous chloride is effected with (PhO)3P at 170°. Interaction of this chloride, (ClCH2)2PCl, with Grignard reagents yields tertiary phosphines, which at slightly above room temperature are unstable, but which may be characterized as oxides or sulfides.
