Asymmetric hydration of alkenes catalyzed by wool‐palladium complex

Abstract

Abstract A wool‐palladium complex has been found to be able to catalyze the asymmetric hydration of 1‐octene to ( S )‐(+)‐2‐octanol and 1‐decene to ( R )‐(+)‐2‐decanol under 1 atm N 2 and at 70°C. The optical yields were greatly affected by Pd content in wool‐palladium complex, reaction time and so on, when the proper conditions were selected, ( S )‐(+)‐2‐octanol and ( R )‐(+)‐2‐decanol could be obtained in 83.2 and 75.6%e.e. optical yield respectively. This chiral natural biopolymer‐palladium complex catalyst was very easy to prepare and could be reused several times without appreciable change in catalytic activity.
