Abstract
N-Acyl dimesylamines. like acyl chlorides, react with 4-dimethylaminopyridine and other tertiary nitrogen bases to give either solid N-acylonium dimesylaminides (1-3). or onium dimesylaminides (e.g. 4) originating from ketene elimination (eq. (5)). The expected acyl transfer properties of N-acylonium dimesylaminides are confirmed by reactions of l a with phenol, 4-nitrophenol, p-thiocresol, and N-methylaniline, and of 1b with phenol, resulting in 0-. S-. or N-acylation, respectively. With exception of compounds 1b and 3, all dimesylaminides could be characterized by their cation and anion mass spectra using field desorption, secondary ion mass spectrometry or fast atom bombardmentKeywords
