Description
Summary:In the presence of supported Pd nanoparticle catalysts, e.g. , Pd/Al 2 O 3 , various diphenylamines could be synthesized through acceptorless formal arylation using NH 3 or its surrogates, e.g. , urea, as nitrogen sources and cyclohexanones as arylation sources. The observed catalysis was truly heterogeneous, and the catalyst was reusable with retention of its high catalytic performance. In the presence of Pd/Al 2 O 3 , various diphenylamines could be synthesized through acceptorless formal arylation using urea as a nitrogen source and cyclohexanones as arylation sources.
