Site-selective nitrenoid insertions utilizing postfunctionalized bifunctional rhodium(ii) catalysts

We report a new strategy for the preparation of dirhodium(ii) complexes with the general formula Rh (A) that allows the isolation of a dirhodium tetracarboxylate complex with a free amino group available for postfunctionalization. The postfunctionalization of this complex enables the incorporation o...

Description
Summary:We report a new strategy for the preparation of dirhodium(ii) complexes with the general formula Rh (A) that allows the isolation of a dirhodium tetracarboxylate complex with a free amino group available for postfunctionalization. The postfunctionalization of this complex enables the incorporation of a variety of functional groups, including double and triple bonds as well as nucleophilic moieties, thus paving the way to new classes of polymeric as well as bifunctional catalysts, and polymetallic complexes. Furthermore, we demonstrate that a urea containing dirhodium(ii) complex enables site-selective nitrenoid insertions by remote hydrogen bonding control.
