A practical and environmentally friendly protocol for the selective oxidation of aryl olefins to arylethanone derivatives by using a Cu(I) catalyst and tert-butyl hydroperoxide (TBHP) has been developed. A series of 2-tert-butoxy-1-arylethanones were obtained in moderate to good yields under mild conditions with high selectivity. In this method, TBHP acts not only as an oxidant but also as the tert-butoxy
已经开发了一种实用且环保的方案,该方案通过使用Cu(I)催化剂和叔丁基氢过氧化物(TBHP)将芳基烯烃选择性氧化为芳烃酮衍生物。在温和条件下以高选择性以中等至良好的收率获得了一系列2-叔丁氧基-1-芳酮。在这种方法中,TBHP不仅起氧化剂的作用,而且还起叔丁氧基和羰基氧源的作用。这使得一步氧化/叔丁氧基化成为可能。还从烯丙基底物合成了各种烯丙基过氧化物。
