Arylcyclopropylcarbenium ions, Ar (c-Pr) CH+, were generated as transient intermediates by laser flash photolysis (LFP) of trans-2, 3-diphenylaziridinimines of aryl cyclopropyl ketones in 2, 2, 2-trifluoroethanol (TFE). The carbocations are thought to arise by way of diazo compounds and carbenes. Rate constants for the unimolecular decay in TFE and for the bimolecular reaction with methanol in TFE were obtained for Ar (c-Pr) CH+ and for ...
