The reaction of gem-aryl-disubstituted methylenecyclopropanes 1 with diaryl diselenide produced the corresponding ring-opened products 1,2-bis(arylselanyl)-3,3-diarylcyclobut-1-ene 4 in the presence of iodosobenzene diacetate in moderate-to-good yields under mild conditions. The further transformation of 4 in the presence of MCPBA has also been examined. ((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451
在二乙酸碘代苯酯存在下,偕-芳基-二取代的亚甲基环丙烷 1 与二芳基二硒化物反应产生相应的开环产物 1,2-双(芳基硒基)-3,3-二芳基环丁-1-烯 4在温和条件下产量良好。还研究了在 MCPBA 存在下 4 的进一步转化。((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
