660-60-6, 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) stearate, cas is 660-60-6,the copper-catalyst compound, it is a common compound, a new synthetic route is introduced below.
General procedure: To a screw-cap reaction tube was added symmetrical N,N?-disubstituted guanidines 1a (0.2 mmol), PdCl2 (5 mol%, 1.8 mg), CuX2 (0.44 mmol). The reaction tube was evacuated and back-filled with CO (three times, balloon). PhCN (2 mL) was added using a syringe and the mixture was heated to the desired temperature with use of an oil bath. When the reaction was completed (detected by TLC), the mixture was cooled to room temperature and vented to discharge the excess CO. After the reaction was completed, the solvent was concentrated by evaporation in vacuo. The residue was purified by flash column chromatography on silica gel to afford the desired product Amides 6a with petroleum ether/ethyl acetate as the eluent.
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) stearate, 660-60-6
