Title:
PRACTICAL METHOD FOR REDUCING ESTERS OR LACTONES
Document Type and Number:
WIPO Patent Application WO/2010/004883
Kind Code:
A1
Abstract:
Disclosed is a method wherein esters or lactones can be respectively reduced into alcohols or diols in the presence of a group 8 (VIII) transition metal complex, a base and a hydrogen gas (H2). By suitably combining the amounts of the group 8 (VIII) transition metal complex and the base to be used, the pressure of the hydrogen gas and the reaction temperature, the reduction method can be extremely practical. This method is a useful alternative to hydride reduction, wherein a design of a highly active catalyst can be performed relatively easily, thereby assuring high productivity.
