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)NacNacZn t Bu ( 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.
