An efficient heterogenised palladium catalytic system for the reductive carbonylation of nitrobenzene to methyl N-phenylcarbamate

A highly active and selective heterogenised homogeneous catalyst, montmorillonitebipyridinepalladium (II) acetate complex for the reductive carbonylation of nitrobenzene to methyl N-phenylcarbamate is reported. With the additional advantages such as ease of filterability and reusability for several cycles with consistent activity and selectivity, the heterogenised system will become practical alternative to the other systems described earlier
