A metal salen complex has been designed to orientate four phenol groups into a tetrahedral array that tightly binds fluoride ion though four OH...F hydrogen bonding interactions.

An electrogenerated heterogeneous chiral (poly)salen-thiophene chromium complex successfully promoted different asymmetric catalytic reactions in an original successive manner, demonstrating its high stability and versatility.

Mechanistic studies have revealed that the isospecific polymerization of epoxides by a discrete salen cobalt(III) catalyst occurs at the surface of the undissolved, crystalline complex.

We report the synthesis of the first 2',3'-diamino substituted uridine derivative with xylo-configuration, its use as starting material for the synthesis of salen-type ligands and the first structurally characterised copper(II) complex thereof.

The design of nanostructured catalysts based on earth-abundant metals that mediate important reactions efficiently, selectively and with a broad scope is highly desirable. Unfortunately, the synthesis such poorly understood. We report here active Ni for reductive amination ketones by ammonia employing hydrogen as reducing agent. key functions Ni-salen precursor complex during catalyst have been...

The first immobilization of a pyrene-tagged chromium salen complex through π-π noncovalent interactions on reduced graphene oxide (rGO) is described. A very robust supported catalytic system obtained to promote asymmetric catalysis in repeated cycles, without loss activity or enantioselectivity. This specific behavior was demonstrated two different reactions (up ten reuses) promoted by complexe...
