摘要

A Kumada cross-coupling reaction involving organomagnesium reagents and (3-methylthio- 2-azaallyl) stannanes with a Ni (0) catalyst provided cyclic nonstabilized (2-azaallyl) stannanes in moderate to good yields. Primary alkyl, aryl, and allylic organomagnesium reagents can be used as the cross-coupling partner. In general, NiCl2dppp in toluene at room temperature provided the shortest reaction times and most consistent yields. The ...
