Abstract

Abstract-Evidence from a specifically labelled acylcarbenium icn of an oxo-transfer reacticn is reported. There has been a considerable interest recently in the study of carbocations directly bonded to electron-withdrawing substitwnts 1-3'8. Direct nmr spectral evidence for a- cyanodiphenylmethyl catian has been obtained'and we have reported nmr spectral data of diphenylmethyl cations bearing an ocarbonyl group under stable ion conditions4. These ...
