P2Et Phosphazene: A Mild, Functional Group Tolerant Base for Soluble, Room Temperature Pd-Catalyzed C-N, C-O, and C-C Cross-Coupling Reactions

摘要

The non-nucleophilic organic superbase P2Et phosphazene can enable a broad range of palladium-catalyzed cross-coupling reactions, including C-C, C-N, and C-O couplings of aryl chlorides, bromides, and iodides at room temperature. The mildness and substrate compatibility of this chemistry can deliver immediate synthetic utility for the preparation of complex molecules.
