Convenient synthesis of symmetrical azines from alcohols and hydrazine catalyzed by ruthenium(II) hydrazone complex in air was written by Gayathri, S.;Viswanathamurthi, P.;Naveen, K.;Murugan, K.. And the article was included in Inorganica Chimica Acta in 2022.Application of 873-76-7 This article mentions the following:
New ruthenium(II) complexes were synthesized from the reaction of ligands namely 10-(2-(benzothiazol-2-yl)hydrazano)phenanthren-9(10H)-one (BTPQ), I or 10-(2-(quinolin-2-yl)hydrazano)phenanthren-9(10H)-one (QHPQ), II with [RuHCl(CO)(EPh3)3] (E = P or As) under reflux. The formation of the complexes was confirmed by anal. and various spectral methods including single crystal XRD anal. The synthesized complexes were applied as catalysts for the synthesis of sym. azines from alcs. and hydrazine hydrate under air. Different substituents in alcs. were well tolerated and wide spectrum of azines were synthesized in good to excellent yields using 1 mol % of catalyst loading. The aerobic catalytic reaction released environmentally benign H2O as the only byproduct. Moreover, a plausible mechanism was provided for the Ru-catalyzed azine synthesis. In the experiment, the researchers used many compounds, for example, (4-Chlorophenyl)methanol (cas: 873-76-7Application of 873-76-7).
(4-Chlorophenyl)methanol (cas: 873-76-7) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Application of 873-76-7
