A Molecular Iron Catalyst for the Acceptorless Dehydrogenation and Hydrogenation of N‑Heterocycles
TLDR
A well-defined iron complex supported by a bis(phosphino)amine pincer ligand efficiently catalyzes both acceptorless dehydrogenation and hydrogenation of N-heterocycles.Abstract:
A well-defined iron complex (3) supported by a bis(phosphino)amine pincer ligand efficiently catalyzes both acceptorless dehydrogenation and hydrogenation of N-heterocycles. The products from these reactions are isolated in good yields. Complex 3, the active catalytic species in the dehydrogenation reaction, is independently synthesized and characterized, and its structure is confirmed by X-ray crystallography. A trans-dihydride intermediate (4) is proposed to be involved in the hydrogenation reaction, and its existence is verified by NMR and trapping experiments.read more

Metal–Ligand Cooperation
TL;DR: Examples of MLC in which both the metal and the ligand are chemically modified during bond activation and 2) Bond activation results in immediate changes in the 1st coordination sphere involving the cooperating ligand, even if the reactive center at the ligands is not directly bound to the metal.

A review of the problem of distinguishing true homogeneous catalysis from soluble or other metal-particle heterogeneous catalysis under reducing conditions
TL;DR: In this article, the authors consider cases in which a discrete transition-metal complex is used as a precatalyst for reductive catalysis and focus on the problem of determining if the true catalyst is a metal-complex homogeneous catalyst or if it is a soluble or other metal-particle heterogeneous catalyst.
