The focus is on developing alternative molecular catalysts using main-group elements and implementing strategic improvements for sustainable hydrogen production. For this purpose, a FB corrole with (2-(2-((4-methylphenyl)sulfonamido)ethoxy)phenyl) group inserted into the meso position (C-10) of corrole, along its high-valent (corrolato)(oxo)antimony(V) dimer, was synthesized. In crystal structure analysis dimer complex, it noted that sulfonamido in ligand periphery sits atop ring. electrochemical evolution reaction (HER) studied compared previously reported which lacks hydrogen-bond donor groups secondary coordination sphere. newly designed molecules, featuring sphere, demonstrated clear superiority HER. Controlled potential electrolysis employed to evaluate charge accumulation associated generation homogeneous three-electrode system presence 50 mM TFA. produced exhibits Faradaic efficiency approximately 80.96%, turnover frequency (TOF) 0.44 h–1, production rate 52.83 μL highlighting effective catalytic activity evolution.

Although diradicals should exhibit a rather small reaction barrier as compared to closed-shell species for activating kinetically inert molecules, the activation and functionalization of carbon dioxide with stable main-group remain virtually unexplored. In this work, we present thorough study on CO2 activation, reversible capture, (de)oxygenation mediated by Group 14 singlet (i.e., diradicaloids) [(ADC)E]2 (E = Si, Ge, Sn) based an anionic dicarbene (ADC) framework (ADC PhC{N(Dipp)C}2; Dipp 2,6-iPr2C6H3). readily undergo [4 + 2]-cycloadditions result in barrelene-type bis-metallylenes [(ADC)E]2(OC═O). The addition is E Ge; thus, detaches under vacuum or at elevated temperature regenerates [(ADC)Ge]2. [(ADC)Sn]2(OC═O) isolable but deoxygenates additional form [(ADC)Sn]2(O2CO) CO. [(ADC)Si]2(OC═O) extremely reactive could not be isolated detected it spontaneously reacts further yield elusive monomeric Si(IV) oxides [(ADC)Si(O)]2(COn) carbonates [(ADC)Si(CO3)]2(COn) (n 1 2) via CO2. molecular structures all compounds have been established X-ray diffraction, mechanistic insight their formation has suggested DFT calculations.
