Abstract
The formation of a dipyranyl ether was observed during a study of the reaction of a γ-unsubstituted pyrylium salt with water in the presence of organic bases. The use, in this reaction, of excess water in conjunction with sodium bicarbonate led to a significant improvement in the synthesis of this ether. The method was extended to the synthesis of dithiapyranyl ether.
