Reactions of arylmethanesulfonyl chlorides catalyzed by dichlorotris(triphenylphosphine)ruthenium(II) (1) have been studied.Desulfonylation occurred when arylmethanesulfonyl chlorides were treated with catalytic amounts of the ruthenium(II) catalyst to give chloromethylarene in high yields.No addition of the sulfonyl chloride to olefin was observed when the reaction was carried out in the presence of an equimolar amount of an olefin such as styrene.However, the rate of disappearance of the sulfonyl chloride was accelerated by addition of an olefin.The desulfonylation is assumed to proceed by a redox transfer promoted homolytic mechanism in the coordination sphere of the catalyst.In the presence of large excess of styrenes, arylmethanesulfonyl chlorides added to the olefins to give 1:1 adducts competitively with the desulfonylation yielding chloromethylarenes.
