Synthesis of Bisquinolone-Based Mono- and Diphosphine Ligands of the Aza-BINAP Type
摘要:
Mono- and bisphosphine ligands based on the 4,4'-bisquinolone structural framework (BIQUIP ligands) were generated by direct microwave-assisted palladium-catalyzed carbon-phosphorus cross-coupling reactions employing the corresponding heteroaryl bromides and diphenylphosphine as substrates.
