oxidation reaction of alcohols toward aldehydes or ketones using catalytic amounts of Fe(NO3)3·9H2O, 4-OH-TEMPO, and NaCl has been developed. Compared with the former catalytic system with TEMPO developed in this group, the new protocol using 4-OH-TEMPO, which is much cheaper on an industrial scale, accomplished the transformation with a higher selectivity, especially for aliphatic alcohols toward aldehydes
已经开发出使用催化量的Fe(NO 3)3 ·9H 2 O,4-OH-TEMPO和NaCl的醇对醛或酮的需氧氧化反应。与该小组中开发的带有TEMPO的旧催化系统相比,使用4-OH-TEMPO的新协议在工业规模上便宜得多,它以更高的选择性实现了转化,特别是对于脂肪醇而言,对醛的转化率更高。α,β-不饱和炔烃或炔酮可以由炔丙醇有效地合成,这在文献中很少进行研究。
