An efficient ruthenium-catalyzed N-alkylation of amines, amides and sulfonamides has been developed employing novel pentamethylcyclopentadienylruthenium(ii) complexes bearing the methylene linked bis(NHC) ligand bis(3-methylimidazol-2-ylidene)methane. The

Paragraph 0085-0087, (2021/04/14)
The invention discloses a synthesis method for catalyzing imine to be reduced into amine, wherein the synthesis method is characterized by comprising the following steps: 1, sequentially putting a sulfonyl imine compound and a catalyst I into a reaction bottle according to a reaction molar ratio of 1:0.01 at normal temperature and normal pressure, adding formic acid and a triethylamine solution according to a volume ratio of 5:2, and reacting in a solvent for 1-15 minutes to obtain a reaction product; and 2, after the reaction in the step 1 is finished, sequentially and slowly adding water and ethyl acetate into an obtained reaction product, sufficiently stirring, standing for layering, extracting a separated water layer by using ethyl acetate, combining an extract of ethyl acetate with a separated organic layer, washing by using saturated edible salt water, and drying by using anhydrous sodium sulfate, evaporating to remove the ethyl acetate solvent to obtain a crude product, and separating and purifying by silica gel column chromatography to obtain the amine compound.

An environmentally friendly route for sulfonamides has been developed. The oxidative coupling of sulfonyl hydrazides and amines was catalyzed by CuBr2 to produce various sulfonamides with the water and nitrogen gas as byproducts. Preliminary experiments revealed that the sulfonyl radical is likely to be involved in the reaction mechanism.
