Abstract

Few 1, 3-oxaselenoles are known. Among these are 2-(acylimino)-1, 3-oxaselenoles which were prepared in 38-56% yield by reaction of gem-dicyano epoxides with potassium selenocyanate. 2 Several spirooxaselenoles have been obtained by treatment of cyclic diones or triones with selenium dioxide at low pH. 3-7 The sulfur analogues, 1, 3-oxathioles, are much more common. 8 2, 4, 5-Triphenyl-2H-l, 3-oxathiole and 2-benzoyl-2, 4, 5- ...
