The chiral phosphine-containing palladacycle, synthesized easily from H-MOP, showed its high catalytic activity as well as asymmetric induction ability in ring-openingreaction of oxabicyclic alkenes with arylboronic acids, providing corresponding products in high yields and high ee.

Water‐promoted palladium‐catalyzed asymmetric ring‐opening (ARO) reaction of oxabenzonorbornadienes with a wide variety of alkoxysilanes has been developed in a one‐pot fashion, yielding cis‐1,2‐dihydronaphthalen‐1‐ols in favourable yields (up to 98%) with gratifying enantioselectivities (up to 98% ee) under mild conditions. To the best of our knowledge, it represents the first example in the ring‐opening
