Reuter, Deborah C.,McIntosh, Joel E.,Guinn, Ashley C.,Madera, Ann Marie

, p. 2321 - 2324 (2007/10/03)

A series of vinyl sulfonamides was synthesized using the Horner reaction of aldehydes and diphenylphosphorylmethane-sulfonamide. The sulfonamide reagent was easily prepared and can be stored indefinitely. The trans orientation about the double bond of the vinyl sulfonamides was the only isomer observed.
