a straightforward and useful procedure leading to a variety of conjugated (E,E)-dienes is reported. The method is based upon sequential coupling reactions of Grignard reagents with the readily available (1E,3E)1l-bromo-4-phenylthio-1,3-butadiene in the presence of NiCl2(dppe).

Abstract
a straightforward and useful procedure leading to a variety of conjugated (E,E)-dienes is reported. The method is based upon sequential coupling reactions of Grignard reagents with the readily available (1E,3E)1l-bromo-4-phenylthio-1,3-butadiene in the presence of NiCl2(dppe).File in questo prodotto:
