EFFECT OF SUBSTITUENTS ON THE NATURE OF THE PRODUCTS OF OXIDATION OF 4H-THIOPYRANS

Article abstract of DOI:10.1007/BF00519811

Depending on the degree of substitution of the thipyran ring, either oxidation at the sulfur atom, which leads to the formation of the 1,1-dioxide, or dehydrogenation of the heteroring in the C₍₄₎ position may occur in the reaction of 4H-thiopy
