摘要

Catalysts of transition metals ionicamente marked.Processes for obtaining and its applications in reau00c7u00d5es of cross couplings used in pharmaceutical and other industries, the present invention relates to catalysts of transition metals ionicamente marked based on imidazolium ionic liquids comprising cations S for application in cross coupling reactions of the type heck, Suzuki and / or similar.Another aspect of the invention relates to the process of obtaining these catalysts of transition metals ionicamente marked based on ionic liquids imidazu00f3lios.More specifically, this invention describes the production and characterization of members of a new class of metal complexes ionicamente marked derived from reaction between chloride ionic liquid, 1 - methyl - 3 - carboximetilimidazu00f3lio (mai.ci) and the salts of Transition Metals Co. To me, for example, m (OAC) ~ 2 ~ (M = Cu, Ni, PD) or other precursors of transition metals.In addition, it has been proved the feasibility of the complex containing palladium catalytic ionicamente marked in Heck and Suzuki coupling reactions, with the activity and higher yields compared with PD (OAC) ~ 2 ~, and numerous other promoters of these reactions previamentes described.
