Abstract

Abstract : A carbodiphosphorane-based iridium pincer complex is demonstrated to rearrange in chlorinated organic solvents under cleavage of a P–C-bond to give a chelating phosphine ylide ligand. Abstract : The carbodiphosphorane-based iridium pincer complex (2 ) is demonstrated to rearrange in chlorinated organic solvents under cleavage of a P–C-bond to give a chelating phosphine ylide ligand. A detailed mechanistic investigation reveals that these types of donor groups are prone for P–C-bond cleavage in the coordination sphere of transition metal hydrido complexes. Finally, complex 2 is demonstrated to be an efficient hydrogen-borrowing catalyst.
