A variety of 1-alkenes are synthesized in 63-91% yields by means of sequential cross-coupling reactions of Grignard reagents with readily available or commercial starting materials, in the presence of transition-metal catalysts.
Three reagents are introduced for radicalallylations: 3-phenylthio-2-bromopropene, 2,3-bis(trimethyl-stannyl)propene, and 3-tris(trimethylsilyl)silylthiopropene.
