Sentences with phrase «copper catalyst»
A copper catalyst refers to a substance, usually made of copper, that helps to speed up or promote chemical reactions. It acts like a helper or facilitator, making the reaction happen more easily and quickly. Full definition
Itami, Musaev, and their team have found that treating copper bromide and a bipyridine ligand with the commercially available oxidizing reagent N - fluorobenzenesulfonimide (NFSI) leads to a new class of dinuclear copper catalysts in which the two Cu (II) centers work collectively to guide NFSI - promoted aromatic C — H imidation.
