1, 1, 1-Trihalophospholines can be prepared from dienes and phosphorus trihalides. Phosphinic and thiophosphinic acid derivatives, respectively, have been obtained by solvolysis of these compounds, whereas 1-oxo-1-chlorophospholines resulted from acetanhydride or sulfur dioxide treatment. The latter products have been converted to phosphine oxides by Grignard-compounds. The reaction described is simpler and more ...
