| Abstract: | The formation of a dipyranyl ether was observed during a study of the reaction of a  -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.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 11, pp. 1454–1455, November, 1970. |
