A series of zinc complexes (1-6) supported by substituted phenalenyl ligands was synthesized by reacting the phenalenyl ligands with diethyl zinc under ethane evolution. The solid state structures of these complexes (1-6) were determined by single crystal X-ray crystallography. Furthermore, the organozinc complexes (4-6) were tested for the polymerization of cyclic esters as efficient catalysts for the ring-opening polymerization of ε-caprolactone (ε-CL) and rac-lactide (rac-LA) in the presence…

TLDR
The selective 1,2‐addition of diethylzinc to the ketone functionality of BMdiPhIK [bis(1‐methyl‐4,5‐diphenylimidazolyl)ketone] is shown, which can serve as a model for reactive intermediates in the catalytic alkylation of ketones with diorganozinc reagents.

TLDR
The thermal properties of complex 3 are explored via thermal gravimetric analysis (TGA), which shows that 3 has a significantly lower decomposition temperature as compared to its bis-ligated counterpart [Zn(L3)2], which gives 3 promise as a single-source precursor to zinc oxide.
