RUTHENIUM CATALYST WHICH IS USED IN RACEMIZATION OR DYNAMIC KINETIC RESOLUTION OF SECONDARY ALCOHOLS

摘要

A ruthenium catalyst is provided to be synthesized simply at high yield, and to perform racemization or dynamic kinetic resolution of secondary alcohols at room temperature in atmosphere stably. A ruthenium complex compound is represented by the chemical formula 1. In the chemical formula 1, R1 and R2 are independently hydrogen or substituted or unsubstituted phenyl, C1-5 alkyl, C2-5 alkenyl or C2-5 alkynyl; R3 is - C (O) -R4 or -Si-R5; R4 is C1-10 alkyl, C3-10 aryl, C1-10 alkoxy or substituted or unsubstituted phenyl; R5 is C1-10 alkyl or C3-10 aryl; X is halogen; and Y and Z are independently hydrogen, carbonyl or phosphine.
