9-benzoylcarbazoles with internal alkynes proceeds efficiently through ortho C–H and C–N bond cleavages. This reaction provides direct access to variously substituted indanone derivatives. The carbazolyl leaving group can be readily recovered and reused for preparing the starting materials. Keywords: annulation; rhodium catalyst; C–H bond cleavage
铑(III)催化的9-苯甲酰基咔唑与内部炔烃的环状偶联通过邻位C–H和C–N键断裂而有效进行。该反应提供了直接获得各种取代的茚满酮衍生物的途径。咔唑基离去基团可以容易地回收并再用于制备起始原料。关键字:环空;铑催化剂 C–H键裂解
