Visible-Light-Induced Metal-Free Regioselective C–H α-Carbonyl Alkylation of 4-Aminocoumarins Using 10-Phenylphenothiazine

Abstract We report a visible-light-induced photoredox method for the regioselective C3 α-carbonyl alkylation of 4-aminocoumarin derivatives. The protocol avoids transition metals and uses 10-phenylphenothiazine (PTH) as an efficient, inexpensive organic photocatalyst in place of...

Metal-coordinated water-assisted enhanced proton conductivity of robust Ni(II)-based 3D/2D metal-organic frameworks

MOFs are considered as frontline support materials for obtaining high proton conduction under humid conditions. This study deals with a 3D and a 2D single-crystal Ni-MOFs. The open-network 3D Ni-MOF (Ni-NDC-BPYH), constructed from 2,6-napthalenedicarboxylic acid (2,6-NDC) and 1,2...
