Regio‐ and Stereoselective 1,2‐Oxyhalogenation of Non‐Conjugated Alkynes via Directed Nucleopalladation: Catalytic Access to Tetrasubstituted Alkenes**
Palladium(II)-catalyzedregio- and stereoselective oxyhalogenation of unactivated internal alkynes is facilitated by a structurally tuned bidentate directing auxiliary, providing rapid access to tetrasubstituted alkenes that can be further diversified into valuable products.
钯 (II) 催化的未活化内部炔烃的区域选择性和立体选择性卤化作用通过结构调整的双齿定向助剂促进,提供快速获得四取代烯烃的途径,这些烯烃可以进一步多样化为有价值的产品。
