Ammonia N-H activation by a N,N′-diamidocarbene
Hudnall, Todd W.,Moerdyk, Jonathan P.,Bielawski, Christopher W.
, p. 4288 - 4290 (2010)
The synthesis and characterization of N,N′-dimesityl-4,6-diketo-5,5- dimethylpyrimidin-2-ylidene is reported; this crystalline N,N′- diamidocarbene was found to split ammonia and engage in other reactions not exhibited by typical N-heterocyclic carbenes.
