Аннотация:
During a study of deuterium-hydrogen exchange of two-ring condensed heterocycles in the presence of a Pt catalyst it was observed that the degree of deuteration decreases in the order benzofuran ≫ naphthalene > benzothiophene. It was found that the degree of deuteration of 2-acetylbenzofuran is 80%, whereas for 2-propylbenzofuran it is only 8%. The degree of deuteration of hydrogenated derivatives decreases in the order coumarin > chromene > dihydrocoumarin; the formation of polydeuterated derivatives is observed for coumarin, whereas products of replacement of one hydrogen atom by deuterium predominate for chromene and dihydrocoumarin. © 1981 Plenum Publishing Corporation.
