Abstract

We herein discuss the use of 1,1-diphosphineamide ligands for the synthesis of mono- and heterobimetallic complexes of Rh(I) and Ti(IV) metal centers. A small library of monometallic species was synthesized and isolated: Ti was used to complex to the amide moiety, whereas Rh was used to bind to the diphosphine. The sequential synthesis of the heterobimetallic species started from isolation of the Ti(amidate) complex followed by addition of Rh precursors in solution. Meticulous analysis of the complexes by NMR spectroscopy allowed stereometric and spatial recognition of these challenging to synthesize and isolate heterobimetallic complexes.
