J. Prust et al., Synthesis and structural characterization of monomeric three-coordinated, beta-diketoiminate organozinc derivatives, ORGANOMETAL, 20(17), 2001, pp. 3825-3828
The monomeric zinc compounds with three-coordinated zinc (dipp)NacNacZnCl (
1), (dipp)NacNacZnMe (2), (dipp)NacNacZntBu (3), and (dipp)NacNacZnPh (4) w
ere prepared under mild conditions in strong coordinating donor solvents. C
ompounds 2-4 have been structurally characterized. The beta -diketoiminate
ligand (2-((2,6-diisopropylphenyl)amino)-4-((2,6-diisopropylphenyl)imino)pe
nt-2-ene) ((dipp)NacNac) acts as a chelating ligand through its two N atoms
, forming a six-membered ring with the zinc atom.
