Suzuki reaction of bromoallenes with arylboronic acids using an air-stable palladium complex Pd(Ph2PCH2CO2)2 as a precatalyst

Suzuki reaction of bromoallenes with arylboronic acids was successfully performed by using an air-stable hemilabile P–O coordinated cyclopalladated complex Pd(Ph2PCH2CO2)2 as a precatalyst, and the corresponding coupling products were obtained in satisfactory to excellent yields. All products are unknown compounds which were characterized by 1H NMR, 13C NMR, IR, and HRMS.
