Abstract

Abstract : Pyridine decorated multi-walled carbon nanotubes have been employed as heterogeneous metal-free catalysts for CO2 hydroboration to methyl borinate under mild conditions. Mechanistic insights have unveiled the non-innocent role of the nanotube carrier in the catalytic performance. Abstract : Pyridine decorated multi-walled carbon nanotubes (N Py -MW) have been successfully employed as a catalyst for the reduction of carbon dioxide to methyl borinate (R2 BO–CH3 ) in the presence of 9-borabicyclo[3.3.1]nonane. N Py -MW represents the first example of a heterogeneous, metal-free and durable catalyst for CO2 hydroboration to methanol. A mechanistic cycle has been proposed on the basis of targeted blank experiments and a quantum chemical study, highlighting the non-innocent role played by the nanotube carrier in the final N Py -MW catalytic performance.
