摘要：

The first microwave-accelerated Hiyama cross-coupling reactions are reported. The reactions of aryl bromides and activated aryl chlorides with PhSi(OMe)(3) [or C2H3Si(OMe)(3)] are complete within minutes using a modified catalyst system that can be prepared from commercially available reagents in situ. The microwave-accelerated reactions proceed under relatively mild conditions (110-115degreesC).
