Suzuki reaction of bromoallenes with arylboronic acids using an air-stable palladium complex Pd(Ph2PCH2CO2)2 as a precatalyst
摘要:
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 H-1 NMR, C-13 NMR, IR, and HRMS. (C) 2010 Xiu Juan Feng. Published by Elsevier B.V. on behalf of Chinese Chemical Society.
