A general method for the synthesis of the title compounds by a one-pot reaction is described. It consists in the double alkylation of lithium diphenylphosphide, obtained by the reaction of triphenylphosphine, lithium and tert-butyl chloride. This procedure can also be used for α-functional alkylating agents.
