Rhodium(III) and Rhodium(II) Complexes of Novel Bis(oxazoline) Pincer Ligands

摘要: A series of novel C2-symmetric bisoxazoline ligands (benbox and benboxMe2) have been prepared. variety coordinatively unsaturated rhodium(III) complexes (3a−g, 4a−g) isolated. Trapping reactions the agostically stabilized complex [RhCl2{(S,S)-ib-benbox(Me2)}] (4d) are described. Metal-to-aryl methyl migration described for [RhMe{(S,S)-ip-benbox(Me2)}][BArf] (11c). Full characterization details reactivity studies air-stable, isolable, mononuclear, paramagnetic rhodium(II) [RhCl2{(S,S)-tb-benbox(Me2)}(H)] (15e) [RhCl2{dm-benbox(Me2)H}] (15g) reported.
