I found the field of Chemistry very interesting. Saw the article Oxidative C-H/N-H Annulation of Aromatic Amides with Dialkyl Malonates: Access to Isoindolinones and Dihydrobenzoindoles published in 2020.0. COA of Formula: C7H5NO4, Reprint Addresses Punniyamurthy, T (corresponding author), Indian Inst Technol Guwahati, Dept Chem, Gauhati 781039, India.. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid
A copper-mediated oxidative C-H/N-H annulation of aromatic amides with dialkyl malonates has been presented to afford synthetically valuable dihydrobenzoindoles and isoindolinones. The reaction proceeds through direct oxidative C(sp(2))H/C(sp(3))-H coupling followed by an intramolecular N-H/C(sp(3))-H dehydrogenative coupling to deliver the target motifs with broad scope and functional group tolerance.
COA of Formula: C7H5NO4. Welcome to talk about 62-23-7, If you have any questions, you can contact Pradhan, S; Roy, S; Banerjee, S; De, PB; Punniyamurthy, T or send Email.
