Pyridine-Based PCP-Ruthenium Complexes: Unusual Structures and Metal–Ligand Cooperation

, 2019
Metal–ligand cooperation (MLC) by dearomatization/aromatization provides a unique way for bond activation, which has led to the discovery of various acceptorless dehydrogenative coupling reactions.

1-Allyl-2,3-cyclopentenopyridinium chloride

IUCrData, 2017
The title compound, C11H14N+·Cl−, was obtained by reaction of 2,3-cyclopentenopyridine and allyl chloride. A network of weak C—H...Cl hydrogen bonds is observed in the crystal structure.

Pyridine-Triggered Fluorescent Switching in Coordination-Induced Allosteric Crystal Transformation

Two zinc complexes with stimuli-responsive properties have been realized in [Zn­(L)2] (1) and [Zn­(L)2(py)]·py (2) (HL = N-(2-hydroxybenzylideneamino)-1,8-naphthalimide, py = pyridine). The crystal-to-crystal transformation between 1 and 2 is achieved by

Nickel-Mediated Dehydrogenative Aryl–Aryl Homocoupling of a Bulky Phosphino-Pyridine

, 2019
Aryl–aryl bond formation through dehydrogenative coupling is an attractive transformation due to the atom and step economy of working with unfunctionalized C–H bonds. Pd catalysts are most common for this process, but Ni complexes have also been targeted
