• Associated context:

  Using 10 mol % of CrCl₃ (CAS 10025-73-7) and phenylmagnesium bromide (CAS 100-58-3), almost no hydrogenation occurred (Table 1, entry 1). The introduction of an N-heterocyclic carbene (CAS 6015-57-2) ligand bearing IPr or CAAC into the system allowed the hydrogenation to proceed at room temperature, forming partial hydrogenation product 2a in more than 30% yield (entries 3 and 4).
