The N-methylation of amines using CO2 and PhSiH3 was efficiently catalysed by a N-heterocyclic carbene copper(i) complex.
使用CO2和PhSiH3对胺进行N-甲基化反应,可以高效地由N-杂环卡宾铜(i)配合物催化。

A variety of methods for regioselective formylation have been examined and exemplified with 3-methylthiophene. Optimal yields and regioselectivity for 2-formylation were obtained with N-formylpyrrolidine (11:1) although up to a 46:1 ratio could be obtained with MeOCHCl2:TiCl4, albeit in lower yield. Optimal 5-formylation (1:1.5) was obtained when using N-formylindoline:(COCl)2.
