Journal ArticleDOI
Accessing Remote meta- and para-C(sp 2 )-H Bonds with Covalently Attached Directing Groups.
TL;DR: This Review compiles the significant achievements made in this field of both meta- and para-selectivity using covalently attached directing groups, which are systematically classified on the basis of their mode of covalent attachment to the substrate as well as their chemical nature.
Journal ArticleDOI
Mechanochemical synthesis of small organic molecules.
TL;DR: A collection of examples on recent developments in organic bond formation reactions like carbon–carbon, carbon–nitrogen (C–N), carbon–oxygen (C-O), carbon-halogen (C –X), etc. is documented.
Journal ArticleDOI
Transition Metal Catalyzed Enantioselective C(sp2)–H Bond Functionalization
TL;DR: This work has shown direct catalytic transformation of C–H bonds to new functionalities has provided a powerful strategy to synthesize complex molecular scaffolds in a straightforward way.
Journal ArticleDOI
Radical-Induced Metal and Solvent-Free Cross-Coupling Using TBAI-TBHP: Oxidative Amidation of Aldehydes and Alcohols with N-Chloramines via C-H Activation.
Tapas Kumar Achar,Prasenjit Mal +1 more
TL;DR: A solvent-free cross-coupling method for oxidative amidation of aldehydes and alcohols via a metal-free radial pathway has been demonstrated.
Journal ArticleDOI
Palladium-Catalyzed Directed meta-Selective C−H Allylation of Arenes: Unactivated Internal Olefins as Allyl Surrogates
Tapas Kumar Achar,Xinglong Zhang,Rahul Mondal,M. S. Shanavas,Siddhartha Maiti,Sabyasachi Maity,Nityananda Pal,Robert S. Paton,Debabrata Maiti +8 more
TL;DR: Experimental and computational studies shed light on the mechanism and point to key steric control in the palladacycle, thus determining product selectivities.
