A novel synthesis of indanes and dihydronaphtalenes based on the intramolecular insertion into C(sp3)−H bonds of gold(I) carbenes generated by retro‐Buchner reaction (decarbenation) has been developed. Deuterium‐labeling and kinetic isotope effect experiments, DFT calculations, and generation of the proposed carbene intermediate from a well‐characterized gold(I) carbenoid support the involvement of
基于分子内插入由逆布氏反应(脱碳)生成的金(I)碳烯的C(sp 3)-H键的新颖合成茚满和二氢萘烷的方法。氘标记和动力学同位素效应实验,DFT计算以及从特征明确的金(I)类胡萝卜素生成拟议的卡宾中间体均支持C(sp 3)-H功能化过程涉及三中心协同机制。
