Trimethylsilylphenyl telluride

Trimethylsilylphenyl telluride, by treatment with benzophenone in MeCN at room temperature, gives compound A which is treated in sequence with phenylacetylene at 100°C to give compound C in 85% yield (route a). The reaction can also be performed in one step by heating a mixture of the telluride (1.2 equiv), benzopheuone (1.0 equiv) and phenylacetylene (1.2 equiv) without solvent at 100°C for 12 h to give C in 93% yield (route b).
