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.
