A general β‐C−H arylation of electron‐deficient thiophenes, pyrroles, and furans has been developed using ligand‐modulated palladium catalyst. The use of a modified norbornene is crucial for reversing the conventional α‐selectivity of these substrates. This method features good yields, high β‐selectivity, and good tolerance of functional groups.

电子缺乏的噻吩，吡咯和呋喃的β-选择性CH芳基化

电子不足的噻吩，吡咯和呋喃的一般β -CH芳基化反应是使用配体调节的钯催化剂开发的。改性降冰片烯的使用对于逆转这些底物的常规α选择性至关重要。该方法具有良好的收率，高的β-选择性和对官能团的良好耐受性。
