Ring-opening polymerization of rac-lactide with aluminum chiral anilido-oxazolinate complexes

A series of dimethylaluminum complexes (L1a-i)AlMe2 (2a-i, where HL1a-i = 2-(2′-ArNH)phenyl-4-R1- oxazoline) bearing chiral, bidentate anilido-oxazolinate ligands have been prepared and characterized. Six of the

Unexpected formation of chiral pincer CNN nickel complexes with β-diketiminato type ligands via C-H activation: Synthesis, properties, structures, and computational studies

Reaction of lithiated chiral, unsymmetric β-diketimine type ligands HL2a-e containing oxazoline moiety (HL2a-e = 2-(2′-R1NH)-phenyl-4-R2-oxazoline) with trans-NiCl(Ph)(PPh3)2 afforded a series of new chiral CNN pincer type nickel complexes (3a-3e) via an unexpected cyclometalation at benzylic or aryl C-H positions. Single crystal X-ray diffraction analysis established the pincer coordination mode and the strained conformation. Chirality, and in one case, racemization of the target nickel complexes were confirmed by circular dichroism (CD) spectroscopy. Electronic structure and band assignments in experimental UV-vis and CD spectra were discussed on the basis of Density Functional Theory (DFT) and time-dependent (TD) DFT calculations.

Modular synthesis of chiral β-diketiminato-type ligands containing 2-oxazoline moiety via palladium-catalyzed amination

A family of new chiral β-diketiminato-type ligands containing oxazoline moiety has been synthesized in moderate to high yields (typically 30-95%) via a Pd-catalyzed amination reaction of chiral oxazolines with primary amines and amides. Notably, (S)-tert-
