Abstract
- The catalytic potential of a large series of easily available metal carbamates (based on thirteen different non-precious metal elements) was explored for the first time in the coupling reaction between 2-aryl-aziridines and carbon dioxide, working under solventless and ambient conditions and using tetraalkylammonium halides as co-catalysts. The straightforward synthesis of novel [NbCl<subscript>3</subscript>(O<subscript>2</subscript>CNEt<subscript>2</subscript>)<subscript>2</subscript>], Nb<superscript>Cl</superscript>, and [NbBr<subscript>3</subscript>(O<subscript>2</subscript>CNEt<subscript>2</subscript>)<subscript>2</subscript>], Nb<superscript>Br</superscript>, is reported. The niobium complex Nb<superscript>Cl</superscript>, in combination with NBu<subscript>4</subscript>I, emerged as the best catalyst of the overall series to convert aziridines with small N-alkyl substituents into the corresponding 5-aryl-oxazolidin-2-ones.
