Journal ArticleDOI
Dehydrogenative Synthesis of Quinolines, 2-Aminoquinolines, and Quinazolines Using Singlet Diradical Ni(II)-Catalysts
Gargi Chakraborty,Rina Sikari,Siuli Das,Rakesh Mondal,Suman Sinha,Seemika Banerjee,Nanda D. Paul +6 more
TL;DR: Insight was carried out into the reaction mechanism which shows that the nickel and the coordinated diamine ligands participate in a synergistic way during the dehydrogenation of alcohols.
Journal ArticleDOI
Accessing Polysubstituted Quinazolines via Nickel Catalyzed Acceptorless Dehydrogenative Coupling
TL;DR: Two environmentally benign methods for the synthesis of quinazolines via acceptorless dehydrogenative coupling of 2-aminobenzylamine with benzyl alcohol and benzonitrile and tetraaza macrocyclic ligands are reported.
Journal ArticleDOI
Metal-Ligand Cooperative Approach To Achieve Dehydrogenative Functionalization of Alcohols to Quinolines and Quinazolin-4(3 H )-ones under Mild Aerobic Conditions.
Siuli Das,Suman Sinha,Deepannita Samanta,Rakesh Mondal,Gargi Chakraborty,Paula Brandão,Nanda D. Paul +6 more
TL;DR: Control experiments and deuterium labelling studies indicate that both copper and the coordinated azo-aromatic ligand participate in a cooperative manner during the catalytic cycle.
Journal ArticleDOI
A nickel catalyzed acceptorless dehydrogenative approach to quinolines
TL;DR: A general, efficient and environmentally benign, one-step synthesis of substituted quinoline derivatives was achieved by acceptorless dehydrogenative coupling of o-aminobenzylalcohols with ketones and secondary alcohols catalyzed by a cheap, earth abundant and easy to prepare nickel catalyst.
Journal ArticleDOI
Achieving Nickel Catalyzed C-S Cross-Coupling under Mild Conditions Using Metal-Ligand Cooperativity.
Rina Sikari,Suman Sinha,Siuli Das,Anannya Saha,Gargi Chakraborty,Rakesh Mondal,Nanda D. Paul +6 more
TL;DR: Taking advantage of ligand centered redox events, the high-energetic Ni(0)/Ni(II) or Ni(I/Ni(III) redox steps were avoided in the catalytic cycle.
