概要
- 論文の詳細を見る
A number of simple reactions of N-(1,3-oxathiol-2-ylidene) ternary iminium salts with active methylene compounds have been studied and are shown to produce thiophene derivatives readily. The reaction intermediates have been isolated and a reaction mechanism is proposed. The cleavage of benzoylthiophenes gave benzoic acid and the thiophenes having no substituents at the C-2 position. Spectroscopic investigation of the thiophene derivatives have shown the effect of 2-dialkylamino group on their spectra.
