title: Boron trifluoride-mediated alkylation of diphenylphosphine with tert-alkyl fluoride.
abstract: [reaction: see text] Treatment of tertiary alkyl fluoride with diphenylphosphine in the presence of a stoichiometric amount of boron trifluoride etherate yields the corresponding tert-alkyldiphenylphosphine despite the coexistence of the strong Lewis acid and the highly coordinating phosphine. Use of diphenyl(trimethylsilyl)phosphine as a nucleophile makes the reaction catalytic in boron trifluoride.
