The development of 1,5-dimethyl-9-azanoradamantane N-oxyl (DMN-AZADO; 1,5-dimethyl-Nor-AZADO, 2) as an efficient catalyst for the selective oxidation of primary alcohols in the presence of secondary alcohols is described. The compact and rigid structure of the azanoradamantane nucleus confers potent catalytic ability to DMN-AZADO (2). A variety of hindered primary alcohols such as neopentyl primary
1,5-二甲基-9- azanoradamantane的发展Ñ -1-氧基(DMN-AZADO; 1,5- d我中号乙基Ñ或-AZADO,2),作为伯醇的存在下选择性氧化的有效的催化剂描述了仲醇的混合物。金刚烷金刚烷核的紧密而刚性的结构赋予了DMN-AZADO强大的催化能力(2)。DMN-AZADO(2)将各种受阻伯醇(例如新戊基伯醇)有效地氧化为相应的醛,而仲醇则保持完整。DMN-AZADO(2)对于在仲醇存在下从伯醇到相应的羧酸的一锅法氧化以及从二醇的氧化内酯化反应也具有很高的催化效率。
