the first metal–organic framework (MOF) that catalyzes N-methylation of amines using 1 atm CO2 and phenylsilane under ambient conditions. Compared with its homogeneous analog, the incorporation of N-heterocycliccarbene (NHC) into the MOF provides more efficient catalysis with improved reaction kinetics, turnovernumbers and recyclability. Moreover, the metalated NHC functionalized MOF achieves direct
我们展示了第一种金属-有机骨架(MOF),它在环境条件下使用1 atm CO 2和苯基硅烷催化胺的N-甲基化。与均相类似物相比,将N杂环卡宾(NHC)掺入MOF可提供更有效的催化,并改善了反应动力学,周转次数和可回收性。此外,金属化的NHC官能化的MOF可以实现带有羧基的胺的直接N-甲基化,而羧基是药物化学中的常见组成部分。
