The effect of Q+OH-was studied, which is formed in NaOH solution used for anion exchange with PTC, on CO substitution of molybdenum hexacarbonyl complex by strong electron donating ligand, 2,2-bipyridine. The change of product yield was discussed according to the amount and types of solvent and PTC, Their compositions, reaction temperature and time, and different cation and anion of PTC.
