under acid-free conditions, a wide variety of hydrocarbons including 1) cycloalkenes, conjugated enynes, electron-deficient alkenes (to afford epoxides), 2) arenes (to afford quinones), and 3) Delta5-unsaturated steroids, Delta4-3-ketosteroids, and estratetraene derivatives (to afford epoxide/ketone derivatives of steroids) in up to 99 % product yield within several hours with up to 100 % substrate conversion
由[Ru(VI)(2,6-Cl2tpp)O2]与Me3SiCl的反应以90%的收率制备的[Ru(IV)(2,6-Cl2tpp)Cl2]是通过X射线晶体学表征的结构明显优于[Ru(IV)(tmp)Cl2],[Ru(IV)(ttp)Cl2]和[Ru(II)(por)(CO)](por = 2,6-Cl2tpp,F20-tpp ,F28-tpp)作为烯烃与2,6-Cl2pyNO(2,6-Cl2tpp = meso-tetrakis(2,6-dichlorophenyl)porphyrinato dianion; tmp = meso-tetramesitylporphyrinato dianion; ttp = meso-tetrakis(对甲苯基)卟啉二价阴离子; F20-tpp =间四(五氟苯基)卟啉二价阴离子; F28-tpp = 2,3,7,8,12,13,17,18-八氟-5,10,15
