In the presence of a catalytic amount of a phosphine, elemental tellurium efficiently inserts into Sn-Sn and Pb-Pb bonds under mild conditions to give the corresponding tellurides R3MTeMR3 (M = Sn, Pb) in quantitative yield. Mechanistic study shows that first a phosphine telluride R′3P=Te is formed via the reaction of R′3P with tellurium, which subsequently reacts with (R3M)2 to produce (R3M)2Te and concomitantly regenerates R′3P to restart another cycle of the catalytic insertion.
