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 ...
In the presence of chiral diamines, the reaction between tin(II) enolates of ketones or 3-acyl-2-oxazolidones and thiosulfonates proceeds smoothly to give the corresponding β-keto sulfides with high enantioselectivity. Further, optically active epoxides are prepared from these β-keto sulfides.

activated by a carbonyl group, alkoxycarbonyl group or a phenyl group, can be replaced by a phenylthio group in the reaction with benzenethiol or its potassium salt. This reaction proceeds in the electron transfer mechanism, and is applicable to the general syntheses of α-phenylthio ketones, α-phenylthio carboxylic esters and α-phenylthio alkylbenzenes from primary nitro compounds.
