Reactions with aziridines. 33. Arene hydrides. Part 1. Highly regioselective ring cleavage of N-acylaziridines by "anthracene hydride" (anion of 9,10-dihydroanthracene). Intermediacy of a carbonyl adduct. Influence of nitrogen inversion on the ring opening
Single-electrontransferreactions between tritylanion and 1-acyl-2,2-dimethylaziridines provide, among other products, the methallyl amides 7 and the triphenylmethanes 8 carrying an amidoethyl chain attached with the tertiary carbon ortho to the triphenylmethane.
