Dimethylphosphine is the organophosphorus compound with the formula (CH3)2PH, often written Me2PH. It is a malodorous gas that condenses to a colorless liquid just below room temperature. Although it can be produced by methylation of phosphine, a more practical synthesis involves the reduction of tetramethyldiphosphine disulfide with tributylphosphine: [Me2P(S)]2 + PBu3 + H2O → Me2PH + SPBu3 + Me2P(O)H WebIn this investigation we evaluated the scope of the intermolecular hydrophosphorylation (Pudovik reaction) of alkynes R1–C≡C–R2(R1= H, alkyl, Ph; R2= alkyl, Ph, COOMe, …
