This article describes the design, optimisation and development of a Suzuki cross-coupling protocol mediated by an efficient palladium-encapsulated catalyst (Pd EnCat) under microwave irradiation. The methodology has been used in both batch mode for classical library preparation and in continuous-flow applications furnishing multigram quantities of material. Described is a method that uses direct focused
A Zwitterionic Palladium(II) Complex as a Precatalyst for Neat-Water-Mediated Cross-Coupling Reactions of Heteroaryl, Benzyl, and Aryl Acid Chlorides with Organoboron Reagents
A zwitterionic palladium(II) complex has been found to be an efficient catalyst for Suzuki–Miyaura cross‐coupling reactions of aryl and heteroaryl organoboron reagents with various heteroaryl chlorides, aryl‐ and heteroarylmethyl chlorides, and aryl acid chlorides in neat water.
