Cross Alkyl-Aryl Versus Homo Aryl-Aryl Coupling in Pdcatalyzed Coupling of Alkyl-Gold(I) and Aryl-X (X = Halide) Carrasco Fernández, Desiré Pérez Temprano, Mónica H. Casares González, Juan Ángel Espinet Rubio, Pablo Catalyst Experiments on palladium catalyzed cross-coupling of [AuMe(PPh3)] with aryl iodides show that Ar–Ar homocoupling products are the main product or an abundant byproduct of the reaction. The percentage of cross-coupling product is higher for aryls with larger p Hammet parameter. The scrambling of organic groups via bimetallic intermediates explains the formation of these products. This scrambling can be observed and the activation energies partially quantified in some cases using as aryl C6Cl2F3, which is relatively reluctant to coupling. 2016-12-14T13:37:27Z 2016-12-14T13:37:27Z 2016-12-14T13:37:27Z 2014 info:eu-repo/semantics/article Organometallics, 2014, 33 (13), p. 3540–3545 0276-7333 http://uvadoc.uva.es/handle/10324/21728 10.1021/om500446x 13 American Chemical Society 33 eng info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ Attribution-NonCommercial-NoDerivatives 4.0 International American Chemical Society
