Palladium-Catalyzed Benzylation of Active Methine Compounds without Additional Base: Remarkable Effect of 1,5-Cyclooctadiene
摘要:
The palladium complex prepared from DPPF and Cp(eta(3)-C3H5)Pd is an effective catalyst for the alkylation of active methine compounds with benzylic carbonates under neutral conditions. The addition of 1,5-cyclooctadiene brought about remarkable improvement in the lifetime of the palladium catalyst, which led to high yields of the desired benzylation products.
