Recently I am researching about TRANSFER HYDROGENATION; ALPHA-ALKYLATION; RUTHENIUM(II) COMPLEXES; PRIMARY ALCOHOLS; KETONES; IRIDIUM; DEHYDROGENATION; REACTIVITY; SECONDARY; BEARING, Saw an article supported by the Ege UniversityEge University [17-FEN-058]. Safety of Pyrazine-2-carboxylic acid. Published in ELSEVIER SCIENCE SA in LAUSANNE ,Authors: Pakyapan, B; Kavukcu, SB; Sahin, ZS; Turkmen, H. The CAS is 98-97-5. Through research, I have a further understanding and discovery of Pyrazine-2-carboxylic acid
A series of monometallic complexes (Ru1-3, Ir-1(-3)) which have N,O-chelating ligand (pyrazine-2carboxylate (1), pyridine-2-carboxylate (2), quinoline carboxylate(3) and bimetallic complexes (Ru-4,Ru-5, Ir-4(,5)) bridged by pyrazine-2,3- dicarboxylate (4) and imidazole-4,5-dicarboxylate(5) were synthesized and characterized by H-1-, C-13 NMR, FT-IR, and elemental analysis. The crystal structure of Ir-2 was determined by X-ray crystallography. The complexes (Ru1-5, Ir1-5) were applied to investigate the electronic and steric effect of ligand in their catalytic activities in transfer hydrogenation and alpha(alpha)-alkylation reaction of ketones with alcohols. The activities of iridium complexes (Ir1-5) were much more efficient than ruthenium complexes (Ru1-5). The highest activity for both reactions was observed for the complex (Ir2 ) with pyridine-2-carboxylate. The Ir hydride species was monitored for both reactions. (C) 2020 Elsevier B.V.
