Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Organometallics called Acceptorless Dehydrogenation of N-Heterocycles and Secondary Alcohols by Ru(II)-NNC Complexes Bearing a Pyrazoyl-indolyl-pyridine Ligand, Author is Wang, Qingfu; Chai, Huining; Yu, Zhengkun, which mentions a compound: 2343-22-8, SMILESS is FC1=CC2=C(NCC2)C=C1, Molecular C8H8FN, Name: 5-Fluoroindoline.
Ru(II) hydride complexes bearing a pyrazolyl-(2-indol-1-yl)-pyridine ligand were synthesized and structurally characterized by NMR anal. and x-ray single crystal crystallog. determinations These complexes efficiently catalyzed acceptorless dehydrogenation of N-heterocycles and secondary alcs., resp., exhibiting highly catalytic activity with a broad substrate scope. The present work established a strategy to construct highly active transition-metal complex catalysts, and provides an atom-economical and environmentally benign protocol for the synthesis of aromatic N-heterocyclic compounds and ketones.
As far as I know, this compound(2343-22-8)Name: 5-Fluoroindoline can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
