1、(保持双键构型!)C=CC-CO有机过酸常用的过酸有：OC6H5-C-O-O-HOCF3-C-O-O-HOH-C-O-O-HC-O-O-HClOCH3-C-O-O-HO过氧甲酸过氧乙酸过氧苯甲酸过氧间氯苯甲酸三氟过氧乙酸+m-ClC6H4CO3HO80 C。Ph-CH=CH-COOEtCH3CO3HCH3COOEtPh-CH-CH-COOEtOCH3CO3HC=CHCHC6H4Cl-pHp-ClC6H4C-COp-ClC6H4CHC6H4Cl-pHHCH3(CH2)5CH=CH2+H2O2二氯甲烷80%CHOCH2CH3(CH2)5-1,2-环氧辛烷C=C+KMnO4CCOH OH+MnO2O

2、H-,H2O顺式氧化!此反应可在实验室制备邻二醇，但产率很低。如果用浓度较大的KMnO4的酸性溶液，结果是得到双健断裂产物：R-CH=CH2RCOOH +CO2KMnO4C=CRHRRKMnO4R-C-R +RCOOHOKMnO4C=CRRHR 酸RRHRC=O +O=C醛 酮KMnO4O=CROHC=CRRHHKMnO4RRC=O+O=C酮甲醛HH碳酸CO2+H2OKMnO4O=COHOHRC CH+KMnO4RCOOH+CO2+MnO2H2O紫红+O3C=CRRHRRRHROOCOCH2ORRHRC=O +O=C醛 酮+H2O2RRHROOCOCH2O2H2O/ZnRRC=O +O=CRO
