MS36-P36 Reactions of C-halogen Bond Activation Mediated by a Rhodium POP ComplexThe reactions of C-halogen bond activation are fundamental steps in organic transformations mediated by transition metal complexes, such as cross-coupling reactions,1as well as in the chemical destruction of halogen-containing organic pollutants, among other processes.
Recently we have shown that the complex RhH{xant(PiPr2)2} (xant(PiPr2)2= 9,9-dimethyl-4,5-bis(diisopropylphosphino)xanthene) reacts with fluoroarenes to give products resulting from processes of C-H bond activations,2 while in the case of chloroarenes the C-Cl bond activation takes place (Figure 1).3 In the present contribution, we will show the preliminary results of the reactivity of the related complex RhCl{xant(PiPr2)2} towards halogenated hydrocarbons. The X-ray diffraction analysis of the products obtained have helped us confirm its reactivity.
