Visible Light–Induced Decarboxylative Radical Addition of Heteroaromatic Carboxylic Acids to Alkenes at Room Temperature in Two‐Molecule Photoredox System

ChemistryOpen, EarlyView.
The photoinduced decarboxylative radical addition of aryl carboxylic acids, including heteroaromatic carboxylic acids, to electron‐deficient alkenes is achieved in a two‐molecule photoredox system using a combination of biphenyl and 9,10‐dicyanoanthracene without heating or base.

Biguanide Hydroiodide as Efficient, Metal‐Free Catalyst for Synthesis of Cyclic Carbonates From CO2 and Epoxides Under Mild Conditions and Its Application to Synthesis of Polymer Bearing Cyclic Carbonate Moiety

Journal of Polymer Science, EarlyView.
We developed that novel use of biguanides as catalysts for the efficient synthesis of five‐membered cyclic carbonates (5CCs) from CO2 and epoxides. Among biguanides and their salts, biguanide hydroiodide showed efficient catalysis for the 5CC formation under mild conditions (25°C–60°C and 1 atm of CO2).

A Critical Review of Limitations and Challenges in Advancement of HNF as a Green Oxidizer for Composite Solid Propellant Formulations

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Hydrazinium nitroformate (HNF) is a chlorine‐free, high‐energy oxidizer with promising applications in green propulsion systems. This review examines the thermal decomposition, combustion kinetics, flame structure, and behavior of HNF, while critically evaluating the current body of literature.
