Description

Application

Copper(I) bromide may be used in the synthesis of the following:
• enantioenriched, functionalized and protected propargylamines
• polyvinylchloride bearing benzoxazine side groups
• polybutadiene having benzoxazine side-groups (PB-Benzoxazine)

General description

Copper(I) bromide is a copper(I) halide. Copper(I) bromide along with N-(n-octyl)-2-pyridylmethanimine participates in the living-radical polymerization of methyl methacrylate. It reacts with various heterocyclic thiones (L) in the presence of triphenylphosphine, to afford the mononuclear complexes of the general formula [Cu(L)(PPh3)2Br].
