Transfer hydrogenation via generation of hydride intermediate and base-free alcohol oxidation activity studies on designed ruthenium complexes derived from NNN pincer type ligands was written by Singh, Prasoon Raj;Maji, Ankur;Singh, Ovender;Singh, Udai P.;Ghosh, Kaushik. And the article was included in Applied Organometallic Chemistry in 2020.Electric Literature of C12H9NO This article mentions the following:
Ruthenium complexes(1-3) were synthesized using pincer-type ligands L1 = (E)-2-((2-phenyl-2-(pyridin-2-yl)hydrazono)methyl)pyridine, L2 = (E)-2-(1-phenyl-2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)pyridine, L3 = (E)-2-(phenyl(2-phenyl-2-(pyridin-2-yl)hydrazono) Me)pyridine. The mol. structures of all the complexes 1, 2 and 3 were determined by using single crystal x-ray diffraction. These complexes showed excellent catalytic activities such as transfer hydrogenation and alc. oxidation Theor. calculations were performed to understand the electronic properties of all the complexes using B3LYP as a function and LANL2DZ as a basis set. In the experiment, the researchers used many compounds, for example, Phenyl(pyridin-2-yl)methanone (cas: 91-02-1Electric Literature of C12H9NO).
Phenyl(pyridin-2-yl)methanone (cas: 91-02-1) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.Electric Literature of C12H9NO
