Crystal Structures of a Series of Complexes Produced by Reaction of Copper(I) Cyanide with Diamines.
Fred B. Stocker et al.
Inorganic chemistry, 38(5), 984-991 (2001-10-24)
A new synthetic procedure developed recently in our laboratories has made possible the synthesis of variety of new complexes of CuCN with diamines. Synthesis was effected by adding the ligand to a solution of CuCN in aqueous sodium thiosulfate. This

Chirality, 27(8), 523-531 (2015-04-25)
A novel pyridineoxazoline (PyOx) containing helical polymer, poly{(-)-(S)-4-tert-butyl-2-[5-(4-tert-butylphenyl)-3-vinylpyridin-2-yl]-oxazoline} (PA), was designed and synthesized to approach the effect of chain conformation on the catalytic property. Its complex with Cu(OTf)(2) , i.e., Cu(II)-PA, was employed to catalyze the homogeneous Diels-Alder (D-A) reaction
