摘要

This paper presents data from a study on the one-pot consecutive double arylation of monosubstituted alkenes with two competing aryl halides. The joint analysis of patterns of the reaction differential selectivity for the products of mono- and double arylation of alkene by the competing aryl halides was carried out. The obtained results cannot be explained in the framework of the commonly accepted linear mechanism that assumes the consecutive activation of aryl halide and alkene in one catalytic cycle. The observed patterns are consistent with the hypothesis of the cooperative nonlinear mechanism of catalysis that suggests the activation of alkene and aryl halide in two coexisting catalytic cycles conjugated by the nonlinear elementary step of interaction of two palladium-containing intermediates.
