Cu(I)-catalyzed diamination of conjugated olefins with tunable anionic counterions. A possible approach to asymmetric diamination.
Various achiral and chiral Cu(I) salts have been prepared from mesitylcopper(I) and investigated for the diamination of conjugated olefins with 1,3-di-tert-butyldiaziridinone as nitrogen source. It has been found that copper(I) phosphate has high catalytic activity for the diamination, and encouraging ee's have also been achieved with chiral phosphates as anionic counterions.
