Abstract

The copper(I) ethylene complex [N{(C3F7)C(Dipp)N}2]Cu(C2H4) (Dipp = 2,6-diisopropylphenyl) has been synthesized by treating [N{(C3F7)C(Dipp)N}2]Cu(NCCH3) with ethylene at room temperature. [N{(C3F7)C(Dipp)N}2]Cu(C2H4) is an air stable, yellow solid. X-Ray crystallographic data of [N{(C3F7)C(Dipp)N}2]Cu(C2H4) show that the 1,3,5-triazapentadienyl ligand coordinates to copper in κ2-fashion. The copper atom adopts a trigonal-planar geometry. [N{(C3F7)C(Dipp)N}2]Cu(C2H4) and [N{(C3F7)C(Dipp)N}2]Cu(NCCH3) effectively catalyze carbene and nitrene transfer to a variety of substrates in high efficiencies.
