Abstract
The novel bisstannane (E)-(1,2-difluoro-1,2-ethenediyl) bis[tributylstannane] 2 was stereoselectively prepared in a high overall yield through a sequential synthetic route from chlorotrifluoroethylene 1. The synthetic application of this novel bisstannane 2 was exemplified in the Pd(PPh3)4/CuI-catalyzed cross-coupling reactions with aryl iodides, yielding (E)-1,2-difluorostilbenes 3 in moderate to high yields.Keywords
