However, it is still worth investigating how to improve catalysts with higher efficiency. Guided by computational and experimental studies, we designed a new type of biphenyl-based phosphine oxide that would form a six-membered phosphonium species as a key intermediate to trigger the catalytic Mitsunobu reaction with a lower barrier of the rate-determining step (30.3 kcal/mol). DFT calculations revealed that only trans dehydration was participated in our catalytic progress and a strong <em>π</em>-<em>π</em> interaction and small spatial constraint of <strong>TS-V</strong> were crucial for high behavior.
