The additional stabilization by the dative PZr bond induces the regio‐ and diastereospecific formation of the α‐zirconated phospholanes 1 on the hydrozirconation of 1‐phenyl‐2,3‐dihydrophosphole. Amazingly, the diphosphanes 3 can be synthesized selectively from the α‐ ( 1 ) as well as the usual α‐substituted product 2 on hydrozirconation with the same chlorophosphanes.
