Abstract

In the presence of KF·2H2O, furoylmethyltriphenylarsonium bromide (1a) or thienoylmethyltriphenylarsonium bromide (1b) reacted with 2-[(un)substituted benzylidene]malononitrile (2) in chloroform at room temperature to give trans-3,3-dicyano-1-furoyl-2-[(un)substituted phenyl]cyclopropane (3a) or trans-3,3-dicyano-1-thienoyl-2-[(un)substituted phenyl]cyclopropane (3b) respectively in good yield with high stereoselectivity. The structures of product 3 were confirmed by IR, MS, 1H NMR, 1H-1H COSY and microanalysis. The relative configuration of product 3 was determined by 1H-1H NOESY technique. The mechanism for the formation of product 3 was also proposed.
