The synthesis and characterization of N,Nâ²-dimesityl-4,6-diketo-5,5-dimethylpyrimidin-2-ylidene is reported; this crystalline N,Nâ²-diamidocarbene was found to split ammonia and engage in other reactions not exhibited by typical N-heterocyclic carbenes.
family of N‐heterocycliccarbenes incorporating an anionic backbone; here, a malonate group. A comprehensive experimental exploration of its chemistry as a free entity (in the form of its lithium salt [1]⋅Li) is presented, and rationalized using DFT calculations at the B3LYP/6‐31+G** level of theory. For the sake of comparison, similar computations were performed on other representative carbene types.
