In 2019,Organic Process Research & Development included an article by Pithani, Subhash; Malmgren, Marcus; Aurell, Carl-Johan; Nikitidis, Grigorios; Friis, Stig D.. Synthetic Route of C51H42O3Pd2. The article was titled 《Biphasic Aqueous Reaction Conditions for Process-Friendly Palladium-Catalyzed C-N Cross-Coupling of Aryl Amines》. The information in the text is summarized as follows:
We herein describe a method for palladium-catalyzed C-N cross-coupling of aryl amines and aryl halides in a biphasic reaction medium composed of 2-methyltetrahydrofuran (MeTHF) and water. By effective solubilization of the inorganic base used, common challenges associated with the scalability of Buchwald-Hartwig aminations using inorganic bases were circumvented. The mildly basic nature of the reaction conditions was highlighted by the facile coupling of a base-sensitive substrate, which could be converted to the corresponding product with a high level of crude purity. The method is operationally simple and displays an improved safety and sustainability profile compared with many alternative strategies for large-scale Buchwald-Hartwig amination. Relying on a commonly available dialkylbiarylphosphine ligand, this approach was applied to three clin. relevant C-N cross-coupling reactions on the hecto- to kilogram scale. The experimental process involved the reaction of Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Synthetic Route of C51H42O3Pd2)
Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3) is the most widely used PdO precursor complex in synthesis and catalysis, in particular as a catalyst for various coupling reactions. Synthetic Route of C51H42O3Pd2 It also used for palladium-catalyzed one-pot synthesis of tricyclic indolines, in the Suzuki-Miyaura coupling of 2-pyridyl nucleophiles and cross-coupling of aryl halides with aryl boronic acids.
