Abstract

We carried out work on N-formylation of amines with CO₂ and PhSiH₃ to produce formamides catalyzed by a copper complex. It was found that the Cu(OAc)₂–bis(diphenylphosphino)ethane (dppe) catalytic system was very efficient for these kind of reactions at room temperature and 1 atm CO₂ with only 0.1 mol% catalyst loading.
