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.
