pyridyltrimethylsilanes allowed us to perform efficient Hiyama cross-coupling with various (het)arylhalides. The reactions proceeded smoothly at room temperature leading to the corresponding functional bis(het)aryl in fair to excellent yields. The presence of pyridine nitrogen alpha to the trimethylsilyl group was requisite to achieve the cross-coupling. [Reaction: see text]
