Reaction of the new aromatic aminophosphine ligand 1-((diethylamino)methyl)-3-((di-tertbutylphosphino)methyl)-2,4,6- trimethylbenzene (4) with [Rh(COE)2Cl]2 (COE = cyclooctene) or with [Rh(ethylene)2Cl]2 at room temperature results in selective carbon-carbon bond activation, yielding the complex ClRh(CH3)[C6H(CH3)2(CH 2N(C2H5)2)(CH 2P(t-Bu)2)] (5). No competing C-H activation was observed during the course of the reaction. When 4 was reacted with (COD)PtCl2 (COD = cyclooctadiene), selective C-H activation of the methyl group situated between the phosphine and amine groups took place, with concomitant intramolecular H transfer to the amine ligand, resulting in the zwitterionic Pt(II) complex Cl2PtCH2(C6H(CH3) 2(CH2NH(C2H5)2(CH 2P(t-Bu)2) (11).
