N-tert-Butylbenzenesulfenamide (1)-catalyzed oxidation of various primary and secondary alcohols to the corresponding aldehydes and ketones was efficiently carried out by using N-chlorosuccinimide (NCS) in the coexistence of potassium carbonate and molecular sieves 4 Å at easy-to-control temperatures ranging from 0°C to room temperature. The present catalytic oxidation was performed without giving any
ñ -叔-Butylbenzenesulfenamide(1)催化各种伯醇和仲醇的成相应的醛和酮的氧化被有效利用进行Ñ氯琥珀酰亚胺(NCS)在碳酸钾和分子筛共存4埃在易于-控制温度范围从0°C到室温。进行本发明的催化氧化而不会损害醇中的官能团,并且由于其温和的反应条件,在形成不稳定醛的醇的氧化中特别有效。此外,伯羟基选择性氧化发生在1-催化的几种二醇的氧化。机理调查建议的次磺酰胺的氯化1通过NCS导致形成一个键的物种,ñ -叔-butylbenzenesulfinimidoyl酰氯(2),其又被氧化的醇中,有碳酸钾的存在下,通过伴随的再生,得到羰基产品催化剂1。
