摘要

2-Hydroxypyridine and related molecules have a large activating effect on the previously reported [PPN][Rh (CO) 4]-based catalytic system for the reductive carbonylation of nitrobenzene to methyl phenylcarbamate (PPN+=(PPh3) 2N+). The effect is not due to the known 2-hydroxypyridine–2-pyridone tautomeric equilibrium, since 4-hydroxypyridine, for which the same tautomeric equilibrium exists, completely inhibits the reaction. A ...
