The pyridinium bond lengths in2and3are essentially identical (differences less than 0.01 Å) despite the group in2being formally a pyridylidene ligand. Only the bond between C2 and C3 in2is a significant 0.03 Å longer than in3 though no bond alteration as in related 2‐ or 4‐pyridylidene complexes was noted; for examples see:
10.1021/ja040075t

A solution of the Ir catalyst (0.2 mmol dissolved in 0.1 mL H2O) was added to a CAN solution (5.5 g 10 mmol in 10 mL H2O) in a 40 mL EPA vial equipped with a pressure transducer. The pressure increase in the closed system was monitored and calibrated by a GC analysis.
Decomposition of the complex seems much less probable because the enhanced reaction rate of complexes2and3compared to IrO2 and because of the first‐order kinetics observed for the reaction. For the activity of IrO2 see:
