An operationally simple and eco-friendly synthetic protocol for [Rh(acac)(CO)(NHC)] complexes is described, with insights into the mechanism provided through operando spectroscopy. The spectroscopic fingerprints of these complexes are correlated to NHCs' electron-donating descriptor values, highlighting a new strategy to evaluate carbenes' electronic properties. An assessment of these complexes in catalytic applications shows promising results in the catalytic hydrogenation of aromatic ketones.
An operationally simple, user and eco-friendly synthetic protocol for the synthesis of [Rh(acac)(CO)(NHC)] complexes is described. Insights into the mechanism are provided using operando spectroscopy. The spectroscopic fingerprints of these complexes are correlated to NHCs reported electron-donating descriptor values, highlighting a new strategy to evaluate carbenes' electronic properties. An assessment of these complexes in catalytic applications is also reported, showing promising results in the catalytic hydrogenation of aromatic ketones.
