using bis(trimethylsilyl) peroxide (BTSP) as oxidant in place of aqueous H(2)O(2). Using a catalytic amount of a proton source, controlled release of hydrogen peroxide helps preserve sensitive peroxorhenium species and enables catalytic turnover to take place. Systematic investigation of the oxorhenium catalyst precursors, substrate scope, and effects of various additives on olefin epoxidation with
用更便宜,更容易获得的无机rh氧化物(例如Re(2)O(7),ReO(3)(OH)和ReO)替代有机金属rh物种(例如CH(3)ReO(3)) (3))可以使用双(三甲基甲硅烷基)过氧化物(BTSP)作为氧化剂代替H(2)O(2)水溶液来完成。使用催化量的质子源,过氧化氢的受控释放有助于保留敏感的过氧化or物质,并使催化转化发生。该论文报道了对氧化or催化剂前体,底物范围以及各种添加剂对用BTSP烯烃环氧化的影响的系统研究。
