Preparation of Trifluorostyrenes via Palladium-Catalyzed Coupling of Arylboronic Acids with Chloro- and Bromotrifluoroethylene
摘要:
A highly efficient and cost-effective method for the preparation of alpha,beta,beta-trifluorostyrene (TFS) and its derivatives is described. The method required only 0.2 mol % of Pd(dba)(2) and 0.4 mol % of (PBu3)-Bu-t and occurred to full conversion within 2.0 h. With this method, a wide range of arylboronic acids were efficiently incorporated to generate alpha,beta,beta-trifluorostyrene derivatives.
