carbonylation of alcohols and unactivated tertiary amines has been demonstrated. The in situ oxidative C–N bond cleavage of tertiary amines was achieved using molecular oxygen as an environmentally benign oxidant providing a user-friendly approach to the synthesis of oxamates. The developed protocol showed excellent activity towards the cyclic as well as aliphatic tertiary amines and long-chain alcohols. This
已证明通过Pd / C催化的醇和未活化叔胺的氧化交叉双羰基化反应可以有效合成草酸酯。在原位使用分子氧作为环境友好的氧化剂提供用户友好的方式来oxamates的合成达到叔胺的氧化C-N键断裂。所开发的方案显示出对环状以及脂肪族叔胺和长链醇的优异活性。这种发达的协议系统是有利的,因为它不含膦配体,不含碱和不含铜,并且Pd / C催化剂易于回收。Pd / C催化剂可循环使用多达五个连续循环。
