Abstract: Anew and facile method for the preparation of diphenylalkylphosphine-boranes 2 was described.Treatment of the available triphenyl phosphine-borane 1 with Na under room temperature,then with propriate alkyl halides below-10℃ afforded seven 2 in good yield,and they were characterized by IR,31P NMR,1H NMRand microanalysis,partially by MS.

Key words: Diphenylalkylphosphine-borane, Triphenylphosphine-borane, Preparation, Alkylation
