Ct. Dalton et al., RECENT PROGRESS TOWARDS THE UNDERSTANDING OF METAL-SALEN CATALYZED ASYMMETRIC ALKENE EPOXIDATION, Topics in catalysis, 5(1-4), 1998, pp. 75-91
The history of the development of useful catalyst systems for the asym
metric epoxidation of alkenes is described. An overview is presented o
f the present state of understanding of the mechanism of the most succ
essful catalysts to date, metal-salen complexes. Recent results from t
he chromium-salen series are presented and their implications for the
mechanism are discussed.
