Proposal accepted: NMR experiments have shown unequivocally that the previously only proposed zwitterionic carbon-carbon Meisenheimer-Wheland complexes are formed in the reaction of 4,6-dinitrobenzofuroxan (DNBF) with 1,3,5-tris(N,N-dialkylamino)benzenes. Increasing the temperature results in a rapid exchange between three homomeric forms of the complex (see scheme; NR2=piperidyl, morpholinyl, pyrrolidinyl).
