34946-82-2, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Copper(II) trifluoromethanesulfonate, cas is 34946-82-2,the copper-catalyst compound, it is a common compound, a new synthetic route is introduced below.
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.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of Copper(II) trifluoromethanesulfonate, 34946-82-2
