3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Formula: C8H10ClNO3

Cobalt complexes containing salen-type pyridoxal ligand and DMSO for cycloaddition of carbon dioxide to propylene oxide was written by Hwang, Saem;Ryu, Ji Yeon;Jung, Sung Hoo;Park, Hyoung-Ryun;Lee, Junseong. And the article was included in Polyhedron in 2020.Formula: C8H10ClNO3 The following contents are mentioned in the article:

Cobalt complexes containing a salen-type pyridoxal ligand with pyridine were synthesized as a new Co(III) catalytic system for the cycloaddition of carbon dioxide. Two cobalt(III) complexes possessing a salen-type pyridoxyl ligand were synthesized by the reaction of pyridoxal ligands (pyr2en = (N,N’-bis(pyridoxylideneiminato)ethylene) and pyr2cy = (N,N’-bis(pyridoxylideneiminato)cyclohexane)) and Co(OAc)2 and characterized by various anal. methods, including IR spectroscopy and high-resolution mass anal. Single-crystal X-ray crystallog. anal. confirmed that the cobalt pyr2en complex had a distorted octahedral structure: the tetradentate Schiff base ligand binds the cobalt metal in one plane, and the metal center adopts an octahedral geometry by the addnl. coordination of acetate and DMSO. The synthesized complexes were used as catalysts in the cycloaddition of carbon dioxide (CO2) to propylene oxide. The catalysts showed high activity for cycloaddition between CO2 and epoxides, even at a low loading (0.5 mol%), in the presence of various cocatalysts. This study involved multiple reactions and reactants, such as 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5Formula: C8H10ClNO3).
