A facile one-pot synthetic route for preparing a series of arylethyl (E)-styrylsulfones or arylethyl arylsulfones is developed. The efficient one-pot DIBAL-H/NaH-mediated route includes reduction of -benzyl--arylketosulfones and retroaldol/aldol or retroaldol reaction of the resulting intermediate. The DIBAL-H/NaH-mediated reaction mechanism has been discussed.
