578743-87-0, 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. [1,3-Bis(2,6-diisopropylphenyl)imidazol-2-ylidene]copper chloride, cas is 578743-87-0,the copper-catalyst compound, it is a common compound, a new synthetic route is introduced below.
Chloro[l ,3-bis(2,6-di-i-propylphenyl)imidazol-2-ylidene]copper(I) (487.59 mg, 0.25 mmol) and silver triflate (64.2 mg, 0.25 mmol) were mixed under nitrogen in 25 mL flask and 10 mL of dry THF were added. Reaction mixture was stirred at RT for 30 minutes. Solution of 1 ,2-bis(diphenylphosphino)benzene (1 1 1.6 mg, 0.25 mmol) in dry THF (5 mL) was added. Reaction mixture was stirred at RT overnight. Resulting mixture was filtered through Celite and solvent was evaporated on rotovap. Recrystallization from CH2CI2 by vapor diffusion of Et20 gave 130 mg (49.6%) of white needle crystals. Structure confirmed by 1H-NMR spectrum of [(IPR)Cu(dppbz)]OTf (CDCb, 400MHz).
The chemical industry reduces the impact on the environment during synthesis,578743-87-0,[1,3-Bis(2,6-diisopropylphenyl)imidazol-2-ylidene]copper chloride,I believe this compound will play a more active role in future production and life.
