A series of six carbonylrhodium (I) complexes of three new and three previously reported di (2-3R-pyrazolyl)-pZ/X-aryl) amido pincer ligands,(RZX) Rh (CO),(R is the substituent at the 3- pyrazolyl position proximal to the metal; Z and X are the aryl substituents para-to the arylamido nitrogen) were prepared. The metal complexes were studied to assess how their properties and reactivities can be tuned by varying the groups along the ligand periphery ...
