Reaction of phenylsulfenamides PhSNR¹R² [R¹R² = (CH₂)₄, (CH₂)₂O(CH₂)₂; R¹ = H, R² = Me₃C] with alkenes, e.g., cyclohexene, in the presence of nitriles RCN (R = Me, Me₂CH, Ph) gave amidines, e.g., I (same R, R¹, R²). CF₃SO₃H and Me₃SiO₃SCF₃ containing a catalytic quantity of CF₃SO₃H were used as promoters. Use of unsym. alkenes gave Markovnikov regiochem. exclusively. The mechanism involved generation of an episulfonium ion followed by attack of the nitrile on the ion in a Ritter-type reaction.. In the absence of nitriles, amines, e.g., II, were formed.

Zhang, Tong published the artcileHigh-efficiency synthesis of sulfenamides and disulfides by electrochemical dehydrogenative coupling, Related Products of catalysis-chemistry, the publication is Environmental Chemistry Letters, database is CAplus.

Catalytic dehydrogenative coupling of thiols with amines to produce sulfenamides and disulfides is an important reaction in the industry. Classical synthesis of sulfenamides involves the reaction between amine nucleophiles and sulfonyl chlorides, which are not widely available, toxic and unstable, and the reaction requires a combination of oxidizing and chlorinating reagents. Here authors describe an environmentally benign protocol for the efficient electrochem. dehydrogenative coupling of thiols with amines or thiols to form compounds possessing S-N or S-S bonds. Authors used potassium iodide as electrocatalyst in methanol for a greener reaction. The reaction operates under ambient conditions in the absence of oxidants, acids/bases or toxic/explosive electrolytes. Results show that most produced sulfenamides R¹SNHR² (R¹ = Ph, benzothiazole-2-yl, 2-thiazolyl, etc.; R² = t-Bu, n-Bu, c-hexyl, etc.) and disulfides RSSR (R = 4-FC₆H₄, 4-MeOC₆H₄, benzothiazole-2-yl, etc.) are generated in yields up to 99%.

Briggs, Edward L. published the artcileSynthesis of Sulfonimidamides from Sulfenamides via an Alkoxy-amino-¦Ë⁶-sulfanenitrile Intermediate, COA of Formula: C10H15NS, the publication is Angewandte Chemie, International Edition (2019), 58(40), 14303-14310, database is CAplus and MEDLINE.

Sulfonimidamides are intriguing new motifs for medicinal and agrochem., and provide attractive bioisosteres for sulfonamides. However, there remain few operationally simple methods for their preparation Here, the synthesis of NH-sulfonimidamides is achieved directly from sulfenamides, themselves readily formed in one step from amines and disulfides. A highly chemoselective and one-pot NH and O transfer is developed, mediated by PhIO in iPrOH, using ammonium carbamate as the NH source, and in the presence of 1 equiv of acetic acid. A wide range of functional groups are tolerated under the developed reaction conditions, which also enables the functionalization of the antidepressants desipramine and fluoxetine and the preparation of an aza analog of the drug probenecid. The reaction is shown to proceed via different and concurrent mechanistic pathways, including the formation of novel S N sulfanenitrile species as intermediates. Several alkoxy-amino-¦Ë⁶-sulfanenitriles are prepared with different alcs., and shown to be alkylating agents to a range of nucleophiles.

Chen, Qian published the artcileCyclization or Hydrogen Migration: Theoretical Study and Experimental Evidence on the Reactivities of Unsaturated Amidyl Radicals, Recommanded Product: N-(tert-Butyl)-S-phenylthiohydroxylamine, the publication is Organic Letters (2005), 7(8), 1625-1627, database is CAplus and MEDLINE.

Theor. calculations (B3LYP/6-31G^*) backed up by deuterated experiments reveal that the N-substituents (R) play a crucial role in determining the reaction pathways of unsaturated amidyl radicals. With the increase of the bulkiness of N-alkyl group, the activation energy for 6-exo cyclization increases steadily, while the activation energy for 1,5-H abstraction remains almost unchanged. Therefore, cyclization occurs exclusively when R is H while 1,5-H migration occurs exclusively when R is t-Bu.

Dodd, Liam James published the artcileInvestigating the Role and Scope of Catalysts in Inverse Vulcanization, Related Products of catalysis-chemistry, the publication is ACS Catalysis (2021), 11(8), 4441-4455, database is CAplus.

Inverse vulcanization is a potential route to the use of the large excesses of elemental sulfur, creating high sulfur content polymers with many potential applications. The addition of a metal diethyldithiocarbamate catalyst was previously found to bring several benefits to inverse vulcanization, making the process more attractive industrially. Herein is reported the establishment and exploration of a library of catalysts for inverse vulcanization. Three ranges of catalysts and up to 32 compounds and their combinations have been investigated. By trialling these alternative catalysts, several tentative deductions about the mechanism have been made. It has been found that stronger nucleophiles give a greater rate enhancement, but with the trade-off that harder bases may promote hydrogen sulfide byproduct formation. Monomer binding by the cation may be a crucial mechanistic step, and it is possible that the catalysts act as phase transfer agents between the immiscible sulfur and organic phases. Addnl., the versatility of catalytic inverse vulcanization has been demonstrated with several different comonomer families.
