Synthesis of organothioacrylonitriles and organoselenoacrylonitriles by reaction of 1-Halo-1-chalcogenoalkenes with CuCN. J. Braz. Chem. Soc. [online]. 2007, vol.18, n.8, pp. 1481-1485.

Reaction of 1-halo-1-organothio or 1-halo-1-organoseleno alkenes with CuCN in NMP as solvent provides a-phenylthio or a-phenylseleno acrylonitriles in good yields. The reaction showed a low stereoselectivity and the products were obtained as E/Z mixtures of isomers.
