Dithioacetals were synthesized from carbonyl compounds and thiols in the presence of polyphosphoric acid trimethylsilyl ester (PPSE) Aldehydes, Ketones, and trioxane could be used as carbonyl compounds, and aromatic, primary, secondary, and tertiary thiols were applicable in the present reaction. The reaction between cyclohexanone and t-butyl thiol afforded a mixture of corresponding dithioacetal and t-butylcyclohexenylsulfide.
在三甲基硅基聚磷酸酯(PPSE)存在下,醛、酮和三恶烷等羰基化合物与芳香族、伯、仲和叔硫醇反应合成了二硫缩醛。环己酮与叔丁硫醇的反应产物为相应的二硫缩醛与叔丁环己烯硫醚的混合物。
