confirmed. Aromatic acids showed high linear selectivity, and aliphatic acids provided branched alkylation products as the major product. The reaction has a broad scope for benzylamines and alkenes. Deuterium labeling experiments suggest that a Rh-carbene intermediate is involved in the case of linear product formation. A different reaction pathway, however, appears to be involved in the case of branched

氘标记实验表明在线性产物形成的情况下涉及 Rh-卡宾中间体。然而,在支链烷基化产物的情况下似乎涉及不同的反应途径,并且该途径似乎也是线性选择性反应中的次要途径。
