The novel method for the synthesis of gem -bisarylthio enamines and α-phenylthio ketones was developed via the coupling of α-substituted vinyl azides with thiols in the presence of tetrabutylammonium iodide (TBAI) as a redox catalyst and electrolyte at ro

The addition reaction of thiol to vinyl azide has been extensively studied. Variously substituted aryl thiols are all viable for this coupling process. The scope of the other partner is successfully expanded from α-aryl vinyl azide to α-alkyl vinyl azide.

A method to access α-thioaryl ketones and α-thioaryl esters employing copper acetate (hydrate) as catalyst and readily accessible diaryl disulfides and β-diketones (or β-keto esters) has been developed. Both alkyl- and aryl-substituted carbonyl compounds can be prepared. Copyright

Photoreactions of aryl phenacyl sulphides were studied, particularly in regard to substituent and solvent effects.In general, aryl phenacyl sulphides Ar1SCH2COAr2 1 = p-tolyl, Ar2 = p-X-C6H4 (X = H, Cl, OH, OMe, and Ph), 2-thienyl, and 2-furyl; Ar1 = 2,4,6-trimethylphenyl, Ar2 = Ph and p-HOC6H4; Ar1 = 2-benzthiazolyl, Ar2 = Ph> underwent photochemical cleavage to disulphides (Ar1S)2 and ketones Ar2COMe.In a few cases a diketone (Ar2COCH2)2 was the only, or major, carbonyl photoproduct.Similar photochemical behaviour was shown by ketosulphides p-Me-C6H4SCH(R)COPh (R = PhCH2, PhCOCH2, and p-Me-C6H4S) and related acetophenone derivatives PhCOCH2SR (R = COPh, SO3Na, and SCH2COPh).In a few instances, from p-Me-C6H4SCH2COAr (Ar = Ph, p-Cl-C6H4, and p-Ph-C6H4), a minor photoproduct was a 2-aryl-5-methylbenzothiophen.Benzyl phenacyl sulphides p-X-C6H4COCH2SCH2Ph (X = OH and OMe) also underwent photo-cleavage to give dibenzyl disulphide and a ketone.Free-radical cleavage products ArCOCH2(.) (Ar = Ph and p-MeO-C6H4) and p-Me-C6H4S(.) were trapped as adducts p-Me-C6H4SC(Ph)2CH2CH2COAr when irradiation of the ketosulphide was carried out in the presence of 1,1-diphenylethylene. 2,5-Diphenylfuran was formed photochemically from 1,4-diphenylbutane-1,4-dione on irradiation in methanol.
