A rare-earth-catalyzed transsulfinamidation of primary sulfinamides with alkyl, aryl, and heterocyclic amines for the synthesis of diverse secondary and tertiary sulfinamides has been realized. Unlike transition metal-catalyzed cross-coupling approaches restricted to non-commercially available disubstituted O-benzoyl hydroxylamines, this newly developed protocol is suitable for diverse readily available primary and secondary amines without any modifications. Excellent catalytic activity and selectivity are achieved with Eu(OTf)3 under mild reaction conditions, which extends the applicability of rare-earth catalysis.

It was reported to develop a simple and convenient method for the Ni/NHC-catalyzed cross-coupling of methyl sulfinates and amines without an acid/base to afford secondary or tertiary sulfinamides in moderate to good yields. The method can provide the desired products with broad substrate scope, good chemoselectivity and good functional group compatibility. The presented approach may enrich the Ni/NHC catalyst system and promote the applications of methyl sulfinates in the organic sulfur chemistry.

Secondary or tertiary sulfinamides are prepared by copper-catalyzed transsulfinamidation of primary sulfinamides with O-benzoyl hydroxylamines. Subsequent oxidations of the resulting products lead to the corresponding sulfonamides. Treatment of N-aryl sulfinamides with O-benzoyl hydroxylamines under copper catalysis provides N-aryl sulfonimidamides.

Copper-catalyzed coupling of thiols with amines was used to synthesize numerous sulfinamides in excellent yields. Sulfenamides or sulfonamides were also formed as reaction byproducts albeit in trace quantities. The procedure is carried out as a one step a

We have developed a simple and convenient method for the cross-coupling of arylboronic acids and their derivatives with DAST-type reagents under mild and metal-free conditions to directly afford sulfinamides in moderate to good yields. Moreover, sulfonamides were obtained after a simple oxidation reaction. The reaction mechanism was investigated by18O-labeling experiments, and the synthetic utility was demonstrated by the sulfoxidation of natural products.

A procedure for the synthesis of N-alkyl-, N-cycloalkyl-, N,N-dialkyl-, and N-arylarenesulfinamides from the corresponding sulfenamides using KF/m-chloroperoxybenzoic acid (CPBA) in CH3CN-H2O is described. High efficiency (fast react
Mild and general method for the synthesis of sulfonamides

, p. 311 - 319 (2008/12/22)
Reaction of methyl sulfinates with lithium amides followed by 3-chloroperoxybenzoic acid oxidation of the resulting sulfinamides provides primary, secondary, and tertiary alkane-, arene-and heteroarenesulfonamides in high yields. This constitutes a mild and facile experimental protocol that avoids the use of hazardous, unstable, or volatile reagents and does not affect the configurational stability of the amines.

Sulfinamides were synthesized from sulfonyl chlorides using a procedure involving in situ reduction of sulfonyl chlorides. The reaction is broad in scope and easy to perform.

Thermolyses and reactions with nucleophiles of S,S-diphenylsulfoximines (1) bearing the following N-sulfur-substituents, i.e., N-p-tolylthio-(b), N-p-tolylsulfinyl-(c), N-(N'-p-tolylsulfonyl-p-toluenesulfinimidoyl)-(d), N-(S',S'-diphenylsulfonio)-(e), N-p-tolylsulfonyl-(f), and N-(N'-p-tolylsulfonyl-p-toluenesulfonimidoyl)-(g), have been examined.The former three sulfoximines (1b-d) are thermally unstable and readily decompose to form diphenyl sulfoxide and diphenyl sulfide by the initial cleavage of the S-N linkage in the original sulfoximines.The latter three sulfoximines (1e-g) fairly stable thermally. 1b-d were found to react with several nucleophiles to afford the corresponding sulfenylated, sulfinylated or sulfinimidoylated products together with N-unsubstituted sulfoximine(1a). 1e was found to react with potassium hydroxide/methanol or chloramine-T/N,N-dimethylformamide to afford diphenyl sulfoxide or S,S-diphenyl-(N-p-tolylsulphonyl)sulfilimine along with 1a in good yields.The latter two sulfoximines (1f,g) were found to be inert in the treatment with a few nucleophiles.S,S-Diphenyl-(N-p-tolylthio)-(1b), -(N-p-tolylsulfinyl)-(1c), -(N-p-toluenesulfinimidoyl)-(1d), and -N-(diphenylsulfonio)-(1e) sulfoximines are all new to sulfoximine chemistry and their chemical behavior and reactivity have not been explored.As a preliminary step, thermal decompositions and reactions of these sulfoximines with several nucleophiles have been examined.
