Synthesis of Unsymmetrical Functionalised Organic Sulphides

, p. 131 - 136 (2007/10/02)
Acyclic thioiminium salts and the condensed thiazolium salts in the presence of aqueous sodium hydroxide as such or under base catalyzed phase transfer catalysis conditions react with appropiate organic halides to provide corresponding unsymmetrical functionalized organic sulphides.With aqueous sodium hydroxide, thioiminium salts provide the disulphides corresponding to incipient thiol.

Huheey's original method for the calculation of substituent electronegativities is modified so that isomeric groups have different electronegativities.The modified form of Huheey's method is then employed to show that our previously published method for anticipating regiochemistry in asymmetric sulfide chlorination, i.e., ΔXP calculations for the α and α' substituents in the sulfide substrates, is successful in all fifty known cases.A new reactivity function (RP) is defined, for the sulfenium ion intermediates, which permits one to anticipate when substrates become inert to chlorine in exhaustive chlorinations conducted in aprotic media.
Synthesis of Functionalised, Unsymmetrical Organic Sulphides - Thioacetamide as a Sulphur Transfer Reagent
Singh, Harjit,Malhotra, Nageshwar,Batra, Manohar S.
, p. 272 - 273 (2007/10/02)
In a novel approach, unsymmetrical organic sulphides (IIa-h) have been obtained from appropriate organic halides and sulphonium salts (I) - a source of incipient thiolate ions.
Reaction of Vinyl Sulphone with α-Metallated Nitriles
Agawa, Toshio,Yoshida, Yasuo,Komatsu, Mitsuo,Ohshiro, Yoshiki
, p. 751 - 755 (2007/10/02)
Vinyl sulphones (1) were subjected to nucleophilic addition by α-lithionitriles (2) and gave cyclized products, 3-oxothian 1,1-dioxides (3) or cyclopropane derivatives (4), in satisfactory yields according to the substituents on the reagents.The cyclopropanation reactions could be extended to the formation of cyclopropyl sulphides (12) - (16) in good yields.
