K⋅⋅⋅F intramolecular chelation: Glycinates with fluorine‐containing substituents on the nitrogen atom were found to be potent substrates for the present diastereoselectivealkylation. Alkylation occurred by way of the corresponding enolate, which possessed a rigid bicyclo [3.3.0] structure. A fluorine atom on the enolate played a pivotal role by constructing an intramolecularinteraction with a potassium

A new tridentate Cu2+ complexbased on (E)-1-(pyridin-2-yl)-N-(quinolin-8-yl)methanimine (PQM) was generated and characterized to support the activation of diazo compounds for the formation of new C–N bonds. This neutral Schiffbase ligand was structurally characterized to coordinate with copper(II) in an equatorial fashion, yielding a distorted octahedral complex. Upon characterization, this copper(II)
