Phosphides lead halides

Treatment of (59) with halides of the higher Group IV elements leads to the analogous phosphines (60). Phosphides continue to be of use in the preparation... 

Besides the phosphide method there is another method for alkylation of phosphine this depends on the intermediate formation of a complex PH3 A1C13 and leads, particularly with long-chain alkyl halides, to satisfactory or high yields of primary phosphines.219... 

White phosphorus reacts with Grignard reagents and organolithium compounds, generating phosphides which give phosphines on hydrolysis phenyl-lithium yields up to 40% of phenylphosphine in this way.361 Alkylation by alkyl halides before hydrolysis leads to unsymmetrical tertiary phosphines.215...
