Synthesis and reactivity of acyclic heterotrinuclear metal complexes

Abstract

Heterobimetallic complexes [L¹(Et)MZn(Et)] (M = Al 1a, Ga 1b; L¹ = {HC(C(CH₃)N(Dipp))₂}, Dipp = 2,6-iPr₂-C₆H₃) and heterotrinuclear complexes [L¹(Et)GaZnM(Et)L¹] (M = Al 2a, Ga 2b) and [L¹(Et)GaZnSi(Et)L²] (2c; L² = {N(Dipp))C(CH₃)CHC(CH₂)(N(Dipp)}) were synthesized by stepwise oxidative addition reactions of ZnEt₂ with heavy carbene analogues and fully characterized including single crystal X-ray diffraction (sc-XRD). Reactions of 2c with B(C₆F₅)₃, NH₃ and PhCH₂OH are also reported.
