Borrowing Hydrogen Amination Reactions: A Complex Analysis of Trends and Correlations of the Various Reaction Parameters

ACS Catalysis, Journal Year: 2022, Volume and Issue: 12(12), P. 7142 - 7198

Published: June 1, 2022

Borrowing hydrogen or the autotransfer amination is a powerful approach to create single C–N bonds, starting from stable and readily available substrates: amines alcohols. It considered as one of most atom-efficient green methods synthesize complex amines. Herein, we attempted arrange array existing data in comprehensive structured manner determine correlations between experimental conditions catalysis outcome both within different groups catalysts defined using machine analysis. For each type N-nucleophiles (aromatic, aliphatic, heteroaromatic amines, amides), efficient working were suggested, including attributing optimal base temperature regime for metal.

Recent Advances in the Protection of Amine Functionality: A Review

ChemistrySelect, Journal Year: 2020, Volume and Issue: 5(23), P. 6861 - 6893

Published: June 17, 2020

Abstract Selective protection of −NH 2 functionality has enormous utility and significance in organic synthesis. Amines are nucleophile basic nature thus vulnerable to react with an extensive range reagents, especially oxidizing, alkylating, carbonyl compounds therefore can require mask these properties the multifunctional molecule during chemical reactions. Protection amine finds important application peptide synthesis, several methodologies have been developed for N‐Protection reaction. Herein, we reviewed recent advances amines (from 2012 till present) hope that this will update current body knowledge aid researchers working area.

Bis(phenoxy-imine) ruthenium(II) carbonyl complexes: syntheses, structures and their catalytic activities for conversion of aldehydes to nitriles

Journal of Coordination Chemistry, Journal Year: 2020, Volume and Issue: 73(12), P. 1848 - 1859

Published: June 17, 2020

Three new ruthenium(II) carbonyl complexes that bear phenoxy-imine chelate ligands, [RN = CH(C6H4O)]2Ru(CO)2 (1: R 2,6-Me2C6H3; 2: 4-OMeC6H4; 3: 4-ClC6H4) have been synthesized. These mononuclear were fully characterized by elemental analysis, FT‒IR, and 1H 13C NMR. Furthermore, the molecular structures of 1-3 determined X-ray crystal diffraction analysis. In presence NaHCO3 as base, Ru showed moderate to good catalytic activities for conversion aldehydes nitriles via dehydration aldoximes.
