Organic letters, 11(10), 2197-2200 (2009-04-22)
CuBr-catalyzed oxidative difluoromethylation of readily available tertiary amines with difluoroenol silyl ethers was performed under mild conditions to afford beta-amine-alpha,alpha-difluoro ketones.
Minhang Xin et al.
Steroids, 75(1), 53-56 (2009-10-20)
An efficient and practical scheme to synthesize 2-methoxyestradiol has been developed. The key step was the copper-mediated methoxylation using ethyl acetate as a co-catalyst to introduce a methoxyl group. These synthetic procedures of four steps from 17beta-estradiol as starting material

Organic letters, 13(19), 5020-5023 (2011-08-31)
A new method for the synthesis of phenanthrenes via ligand-free CuBr(2)-catalyzed coupling/cyclization of terminal alkynes with N-tosylhydrazones derived from o-formyl biphenyls has been developed. This new synthesis has wide range of functional group compatibility.

Advanced materials (Deerfield Beach, Fla.), 24(18), 2469-2473 (2012-04-11)
A new multiferroic material, CuBr(2) , is reported for the first time. CuBr(2) has not only a high transition temperature (close to liquid nitrogen temperature) but also low dielectric loss and strong magnetoelectric coupling. These findings reveal the importance of
