Abstract

BY J. MEIJER, P. VERMEER, H. D. VERKRUIJSSE and L. BRANDSMA (Department of Organic Chemistry of the University, Croesestraat 79, Utrecht) ... Interaction between di( I-alkynyl) sulfides (1) and sodium sulfide, selenide or tel- luride in mixtures of liquid ammonia and methanol or dimethylformamide and methanol gives 1,4-dithiins (2), 1,4-thiaselenins (3) and 1,4-thiatellurins (4). ... We have observed that di(1-alkynyl) sulfides (la-f) react with sodium sulfide, ...
