The sulfoxidation reaction catalyzed by CoBr2 complexes, under the magnifying glass of green parameters

, p. 44 - 54 (2018)
Different cobalt (II) and nickel (II) species were used as catalysts in sulfoxidation reactions giving excellent yields and high chemoselectivity. Among the cobalt (II) species, both γ-cyclodextrin complexes synthesized in ethyl acetate or dichloromethane solvents were very good catalysts, while γCDNiBr2 synthesized in ethyl acetate was the best of Ni (II) species. Sulfoxidation takes place with high chemoselectivity in the presence of other groups such as aldehyde. Good results were obtained when these reactions were analyzed using green chemistry metrics. Techniques as FT-IR, UV–vis Diffuse Reflectance, colorimetry, TGA, flame atomic absorption, potentiometric halide titration, and elemental analysis were used to characterize novel complexes. The change of solvent in the synthesis of complexes produces positive effects in holistic green metrics.

A safe, practical and eco-friendly method for the switchable synthesis of sulfoxides and sulfones through visible-light-initiated oxygenation of sulfides at ambient temperature under transition-metal-, additives-free and minimal solvent conditions. The synergistic catalytic efforts between CF3SO2Na and 2-butoxyethyl ether represents the key promoting factor for the reaction. This journal is
Electrochemical oxygenation of sulfides with molecular oxygen or water: Switchable preparation of sulfoxides and sulfones
Li, Jin-Heng,Li, Yang,Sun, Qing,Xue, Qi,Zhang, Ting-Ting
supporting information, p. 10314 - 10318 (2021/12/17)
A practical and eco-friendly method for the controllable aerobic oxygenation of sulfides by electrochemical catalysis was developed. The switchable preparation of sulfoxides and sulfones was effectively controlled by reaction time, in which both molecular oxygen and water can be used as the oxygen source under catalyst and external oxidant-free conditions. The electrochemical protocol features a broad substrate scope and excellent site selectivity and is successfully applied to the modification of some sulfide-containing pharmaceuticals and their derivatives.

Electrochemical Scalable Sulfoxidation of Sulfides with Molecular Oxygen and Water
Cheng, Zhen,Gao, Xinglian,Yao, Lingling,Wei, Zhaoxin,Qin, Guohui,Zhang, Yonghong,Wang, Bin,Xia, Yu,Abdukader, Ablimit,Xue, Fei,Jin, Weiwei,Liu, Chenjiang

An efficient and chemoselective synthesis of sulfoxides through the electrooxidation of sulfides has been well developed. This protocol takes advantage of electricity as the terminal oxidant and of molecular oxygen and water as the oxygen atom sources. A variety of structurally diverse sulfoxide compounds are assembled in moderate to excellent yields. The scaled-up reactions at 6–20 mmol show the good practicability and application potential of this methodology. A possible free radical mechanism has been proposed to rationalize the reaction procedure.
