The copper-catalyst compound, cas is 34946-82-2 name is Copper(II) trifluoromethanesulfonate, mainly used in chemical industry, its synthesis route is as follows.,34946-82-2
To a solution of 2.00 g (4.82 mmol) of the above ieri-butyl ester in dimethylsulfoxide (15 mL) is added 1.10 mL (10.1 mmol) of dimethylethylenediamine followed by 0.983 g (9.64 mmol) of sodium methanesulfinate, and 1.74 g (4.82 mmol) of copper (II) triflate. The mixture is heated at 130 C under argon for 2 hours. The mixture is cooled to room temperature and diluted with water causing a solid to precipitate from solution. The formed solid is collected by filtration, washed with water, and dried on the filter pad. The residue is purified by flash silica gel chromatography to give 1.03 g (52.0%) of (5′- methanesulfonyl-3′-nitro-3,4,5,6-tetrahydro-2H-[l,2′]bipyridinyl-4-ylmethyl)-carbamic acid ie/ -butyl ester as a brown resin.
As the rapid development of chemical substances, we look forward to future research findings about 34946-82-2
