It was found that cesium carbonate has a unique catalytic ability on the reaction of carbonyl compounds with diphenyl diselenide to give the corresponding α-phenylseleno carbonyl compounds in moderate to good yields. Similarly, the α-phenylthiolation of carbonyl compounds with diphenyl disulfide was promoted by the cesium carbonate catalyst.

For the cesium carbonate-catalyzed α-phenylthiolation of carbonyl compounds with diphenyl disulfide, the yields of the α-phenylthio carbonyl compounds were dramatically improved by the addition of ...
