Czegeni, Csilla Eniko published the artcileSelective hydration of nitriles to corresponding amides in air with Rh(I)-N-heterocyclic complex catalysts, Formula: C27H39ClN2, the publication is Catalysts (2020), 10(1), 125, database is CAplus.
A new synthetic method for obtaining [RhCl(cod)(NHC)] complexes (1–4) (cod = η4 -1,5- cyclooctadiene, NHC = N-heterocyclic carbene: IMes, SIMes, IPr, and SIPr, resp.) is reported together with the catalytic properties of 1–4 in nitrile hydration. In addition to the characterization of 1–4 in solution by 13C NMR spectroscopy, the structures of complexes 3, and 4 have been established also in the solid state with single-crystal X-ray diffraction anal. The Rh(I)-NHC complexes displayed excellent catalytic activity in hydration of aromatic nitriles (up to TOF = 276 h-1) in water/2-propanol (1/1 volume/volume) mixtures in air.
