Abstract: In this study we synthesized a series of sixteen bis(imino)pyridines (BIPs) starting from 2,6-diaminopyridine and various aromatic aldehydes, and evaluated their antioxidant, antibacterial, antifungal and acetylcholinesterase (AChE) inhibitory activity. The chemical structures were elucidated by… read more here.

DOI: 10.1021/acs.organomet.8b00183
Abstract: The 1,4-dihydropyridinate complex [(4-Bn-HBIP)Zn(Bn)], readily available through the highly selective reaction of a 2,6-bis(imino)pyridine ligand with dibenzylzinc, contains two distinct reactive centers. One of them is the σ-organometallic benzylzinc moiety, which reacts with weak protic… read more here.

Abstract: We recently reported a bis(imino)pyridine (or pyridine diimine, PDI) manganese precatalyst, (Ph2PPrPDI)Mn (1), that is active for the hydrosilylation of ketones and dihydrosilylation of esters. In this contribution, we reveal an expanded scope for 1-mediated… read more here.
