Triazatriangulenium cations: Highly stable carbocations for phase-transfer catalysis.
Highly stable triazatriangulenium carbocations, of pK(R+) higher than 20, can be used as novel phase-transfer catalysts for several classical organic reactions, their intrinsic stability in strongly basic and nucleophilic conditions rendering this novel use feasible.
