de las Heras, Laura A.; Esteruelas, Miguel A.; Olivan, Montserrat; Onate, Enrique published the artcile< Rhodium-Promoted C-H Bond Activation of Quinoline, Methylquinolines, and Related Mono-Substituted Quinolines>, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is rhodium diphosphinoxanthene pincer complex carbon hydrogen bond activation quinoline; diphosphinoxanthene rhodium quinolinyl pincer complex preparation crystal structure; mol structure diphosphinoxanthene rhodium quinolinyl pincer complex.
The C-H bond activation of methylquinolines, quinoline, 3-methoxyquinoline, and 3-(trifluoromethyl)quinoline promoted by the square-planar Rh(I) complex RhH{�-P,O,P-[xant(PiPr2)2]} [1; xant(PiPr2)2 = 9,9-dimethyl-4,5-bis(diisopropylphosphino)xanthene] was systematically studied. The activation of the heteroring is preferred over the activation of the carbocycle, and the activated position depends upon the position of the substituent in the substrate. Thus, 3-, 4-, and 5-methylquinoline reacts with 1 to quant. form square-planar Rh(I)-(2-quinolinyl) derivatives, whereas 2-, 6-, and 7-methylquinoline quant. leads to Rh(I)-(4-quinolinyl) species. By contrast, quinoline and 8-methylquinoline afford mixtures of the resp. Rh(I)-(2-quinolinyl) and -(4-quinolinyl) complexes. 3-Methoxyquinoline displays the same behavior as that of 3-methylquinoline, while 3-(trifluoromethyl)quinoline yields a mixture of Rh(I)-(2-quinolinyl), -(4-quinolinyl), -(6-quinolinyl), and -(7-quinolinyl) isomers.
