Crystal and Molecular Structure and Reactivity of Jacobsen Epoxidation Catalyst N,N’-di(3-t-butyl-5-methyl salicylidene)cyclohexanediamine manganese(III)chloride·MeCN

摘要

The molecular structure of Jacobsen epoxidation catalyst N,N’-di(3-t-butyl-5-methyl salicylidene)cyclohexanediamine manganese(III)chloride·MeCN is determined by single crystal X-ray and UV-Vis analysis. The epoxidation of dihydronaphthalene and dimethylchromene with amorphous and crystalline catalyst gave comparable enantiomeric excesses of 69 % and 92 % respectively.
