From CO₂ to CS₂: a theoretical investigation of the cycloaddition to aziridines mediated by metal-free porphyrin-based catalytic systems

Abstract

A detailed computational analysis of the synthesis of thiazolidine-2-thiones by the CS2 insertion into the three membered aziridine rings is here reported. DFT studies highlighted the feasibility of the atom-efficient...

Hematin supported on Colour Catcher®: a biodegradable heterogeneous catalyst for halogen-free CO2 cycloadditions

“…The intrinsic coloration of porphyrins enabled to be effectively immobilized onto CC sheets, resulting in a material that exhibited strong performance in sensing 42,[44][45][46] and catalysis. 43 Given our expertise in utilizing metal porphyrins and free porphyrins in combination with ammonium salts or chloride sources both in homogeneous 27,[47][48][49][50][51][52] and heterogeneous 53 CO 2 cycloadditions, we have studied the catalytic activity of environmentally-friendly porphyrins derived from natural sources, such as hemin and hematin.…”
