The First Phosphine-Catalyzed Insertion of Tellurium into Sn-Sn and Pb-Pb Bonds: A Simple and Efficient Route to R3MTeMR3 (M = Sn, Pb)

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.

REACTIONS OF DIMETHYLSELENADIAZOLE AND ALKYLTIN DERIVATIVES

Reactions of 4,5-dimethyl-1,2,3-selenadiazole with hexaalkylditins or trialkyltin anion followed by quenching with trialkyltin chloride affords only dimethylacetylene and bis(trimethyltin) selenide.Implications of these results in relation to possible syntheses of selenatellurafulvalenes are discussed.
