The preparation of dithioacetals by the reaction of methylene compounds with S-methyl methanesulfonothioate on Al2O3-KF is described. Microwave irradiation without solvent provides a powerful activation. Potential antiviral phosphona

The sulfenylation of some half-esters of malonic acids and some α-sulfonylmalonic esters with several sulfenylating reagents was investigated.Evidence was provided that in the case of the half-esters, in which NaH-dimethyl sulfoxide was employed, the formation of α,α-disulfenylated carboxylic esters may occur by two different reaction sequences, initiated either by dianion formation or decarboxylation.It is shown that, in the case of the α-sulfonylmalonic esters, in which diazabicyclooctane in refluxing toluene was employed, two competitive reactions may take place: de-ethoxycarbonylation or desulfonylation, both followed by sulfenylation.
