The mechanism of the Rh‐catalyzed oxidative coupling cyclization of 2,3‐allenols has been studied by DFT calculations. The whole process of the current reaction involves the nucleophilic cyclic oxyrhodation/ stereodefined carborhodation/ β ‐H elimination/ reductive elimination. Calculated results reveal that the carborhodation step is not only the rate‐limiting step but also determines the stereo‐selectivity.
