通过反应成功合成了稳定的空气稳定的μ-氧桥双核路易斯酸钛(IV)Salophen全氟辛烷磺酸[{Ti(salophen)H 2 O} 2 O] [OSO 2 C 4 F 9 ] 2(1)。AgOSO 2 C 4 F 9制备Ti IV(盐基)Cl 2并通过IR,NMR和HRMS等技术进行表征。该复合物可在一年中稳定地暴露于空气中,并具有良好的热稳定性和在极性有机溶剂中的高溶解度。该配合物还具有相对较强的酸度,强度为0.8
The formation of C–S bonds using cheap, stable and odorless sulfonylchlorides and widely sourced and less toxic alcohols with the assistance of ADDP is reported. This method is suitable for a broad substrate scope and tolerates a broad range of functional groups. Additionally, our protocol provides a green and convenient methylating method utilizing methanol or methanol-d4 and allows trideuteromethylthiolation
In the presence of iron dust, diaryl disulfides react with -bromo carbonyl compounds to obtain -arylthio carbonyl compounds in good yield at 90 degrees C under an N-2 atmosphere, using commercial dimethylformamide (DMF) as solvent. The possible reaction mechanism is that the disulfide is reduced by iron dust to give ArSFeSAr and then reacted with -bromo carbonyl compounds to give product -arylthio carbonyl compounds and FeBr2.
