acids with aldehydes and alpha-ketoesters are described. Our study demonstrated that palladacycles were highly efficient, practical catalysts for these addition reactions. The work described here not only opened a new paradigm for the application of palladacycles, but may also pave the road for other metalacycles as practically useful catalysts for such addition reactions including asymmetric ones.

描述了基于阴离子四电子供体的Palladacycle催化的芳基硼酸与α,β-不饱和酮的1,4-加成和芳基硼酸与醛和α-酮酸酯的1,2-加成。我们的研究表明,palladacycles是这些加成反应的高效,实用催化剂。此处描述的工作不仅为Palladacycles的应用开辟了新的范式,而且还可能为其他金属环烷铺平道路,因为金属环对于此类加成反应(包括不对称催化剂)实际上是有用的催化剂。[反应:请参见文字]。
