1-dicyano-2-(2-furyl)ethene and allyltributylstannane in the presence of phenanthrene in aqueous acetonitrile afforded regioselectively 5,5-dicyano-4-(2-furyl)-1-pentane. Photoreactions of the other furyl and thienyl dicyanoethene derivatives with allylic stannanes gave the corresponding allylic products in good yields.
