In the presence of a catalytic amount of dichlorotris(triphenylphosphine)ruthenium(II), the reactions of arenesulfonyl chlorides with allyl phenyl sulfide and allyl phenyl selenide proceeded smoothly to give allyl phenyl sulfone in high yield as well as the corresponding diphenyl disulfide or diphenyl diselenide. An SH2′-type mechanism involving the arenesulfonyl radical is proposed.
在催化量的二氯三(三苯基膦)钌(II)存在下,芳烃磺酰氯与烯丙基苯基硫醚和烯丙基苯基硒化物的反应顺利进行,以高收率得到烯丙基苯基砜以及相应的二苯基二硫醚或二苯基二硒化物. 提出了涉及芳烃磺酰基的 SH2' 型机制。
