Synthesis and Structural Characterization of Monomeric Three-Coordinated β-Diketoiminate Organozinc Derivatives†

The monomeric zinc compounds with three-coordinated zinc (dipp)NacNacZnCl (1), (dipp)NacNacZnMe (2), (dipp)NacNacZntBu (3), and (dipp)NacNacZnPh (4) were prepared under mild conditions in strong coordinating donor solvents. Compounds 2−4 have been structurally characterized. The β-diketoiminate ligand (2-((2,6-diisopropylphenyl)amino)-4-((2,6-diisopropylphenyl)imino)pent-2-ene) ((dipp)NacNac) acts as a chelating ligand through its two N atoms, forming a six-membered ring with the zinc atom.
