Herein, by applying visible-light photoredox catalysis, we have achieved the catalytic deaminative alkylation of diphenylphosphine and phenyl phosphine with benzylamine-derived Katritzky salts at room temperature. The use of Eosin Y as photoredox catalyst and visible light can largely promote the reaction. A series of unsymmetrical tertiary phosphines were successfully synthesized, including phosphines with three different substituents that are otherwise difficult to obtain.

Secondary and tertiary phosphines (RR'PH; R2R'P) may be synthesized by alkylation of primary or secondary phosphines with organo halides (R' = Et, n-C7H15, Bz, Me3Si; X = Cl, Br) in the presence of Schwesinger bases as auxillary bases in high yields.Alkylation of diphenylphosphine with alkylene dihalides and Schwesinger bases affords alkylendiphosphines. Key words: Alkylation; secondary and tertiary phosphines; Schwesinger bases.
