A convenient one-pot synthetic method for the formation of alkyl aryl sulfides from various alkyl halides and lithium aryl thiolates that are prepared in situ by direct halogen-lithium exchange is reported. In particular, the method overcomes many of the problems encountered in previous reports; it is very quick, catalyst-free, and does not involve use of unstable aryl thiols.

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.
