The title compounds are prepared in good yields from ethoxycyclopropenium fluoroborate and the corresponding alcohols, diols, or dithiols with added triethylamine. Cyclopropenone reacted with dithiols in the presence of trifluoroacetic acid to afford dithioacetals in lower yields, while diols were inert under similar reaction conditions.
标题化合物是由乙氧基环丙烯氟硼酸盐和相应的醇、二元醇或二硫醇加三乙胺制备而成,收率很高。环丙烯酮在三氟乙酸存在下与二硫醇反应,生成的二硫代乙醛收率较低,而二元醇在类似的反应条件下则呈惰性。
