摘要

α, β-Unsaturated thioaldehydes and thioketones, R1CH CH-C (S) R2, are prepared in situ by the reaction between the corresponding carbonyl compounds and bis (dimethylaluminum) sulfide. These compounds undergo [4+ 2] self-dimerization reactions in which one molecule serves as the heterodiene component and the other as the dienophile to afford different types of dimeric products depending on the R1 and R2: 1, 2-dithiin and 1 ...
