Reactivity of Cyclic (Alkyl)(amino)carbenes (CAACs) and Bis(amino)cyclopropenylidenes (BACs) with Heteroallenes: Comparisons with their N-heterocyclic Carbene (NHCs) Counterparts
Similarly to NHCs, CAAC(a) and BAC(a) react with CO(2) to give the corresponding betaines. Based on the carbonyl stretching frequencies of cis-[RhCl(CO)(2)(L)] complexes, the order of electron donor ability was predicted to be CAAC(a) ≈ BAC(a) > NHCs. When the betaines ν(asym)(CO(2)) values are u...
