The first examples of direct palladium-catalyzed arylation and heteroarylation of cyclopropenes have been demonstrated. This method allows for efficient synthesis of various tetrasubstituted cyclopropenes, incuding nonracemic cyclopropenes, which are not available via known asymmetric cyclopropenation methods. Mechanistic studies strongly suggest an electrophilic path for this Heck-type transformation
已经证明了直接钯催化的环丙烯芳基化和杂芳基化的第一个例子。该方法允许有效合成各种四取代的环丙烯,包括非外消旋环丙烯,这是通过已知的不对称环丙烯化方法无法获得的。机理研究强烈暗示了这种 Heck 型转化的亲电路径。
