The room temperature sequential formation of two C-C bonds by reaction of aromatic or aliphatic Grignard reagents with (E)- or (Z)-1-bromo-2-phenylthioethene in the presence of nickel(II) or palladium(II) catalysts provides a novel stereospecific route to a variety of (E)- or (Z)-olefins of the R-CH=CH-R and R1-CH=CH-R2 type, with a stereoselectivity higher than 99percent for the (E) isomers and in the range 95-98percent for the (Z) isomers.
