R. Hunter et al., Aerobic epoxidation of alkenes catalysed by cobalt(II) 1,1,1,5,5,5-hexafluoroacetylacetonate or cobalt(II) benzoylacetonate, SYN COMMUN, 30(24), 2000, pp. 4461-4466
The aerobic epoxidation of terminal or electron deficient alkenes with an a
ldehyde does not proceed with cobalt(II) acetylacetonate but goes to comple
tion with the cobalt(II) benzoylacetonate and cobalt(II) 1,1,1,5,5,5-hexafl
uoroacetylacetonate complexes.
