An efficient synthesis of cis-1,2-dicyanoalkenes by the reaction of 1,1-bis(benzenesulfonyl)alkenes with KCN was developed. This reaction was conducted in the presence of tetrabutylammonium bromide and NH4Cl/K3PO4 under phase-transfer conditions. A series of cis-1,2-dicyanoalkenes were obtained in good to high yields. Further transformation of the obtained product allows for access to imide and dicarboxylic acid compounds.

The use of less basic chiral amine catalysts for highly enantioselective conjugate additions of aldehydes to vinyl sulfones was reported. The results show that the addition of aldehydes to α-cyano vinyl sulfones takes place at -40°C to give alcohols. The
