Phosphine: Difference between revisions

Primary phosphines are typically prepared by alkylation of phosphine. Simple alkyl derivatives such as [[methylphosphine]] (CH₃PH₂) are prepared by alkylation of alkali metal derivatives MPH₂ (M =is Li, Na, or K). Another synthetic route involves treatment of the corresponding chlorophosphines with hydride reagents. For example, reduction of [[dichlorophenylphosphine]] with [[lithium aluminium hydride]] affords [[phenylphosphine]] (PhPH₂).
