The kinetics of formation of hemiacetals in the Fe(III) coordination sphere resulting from the reaction of Fe(III)
tris-hexafluoroacetylacetonate with methanol has been studied by the stopped-flow method. Two molecules of methanol and coordinated hexafluoroacetylacetonate anion (HFA−) take part in the rate-determining step. The effect of the second molecule of alcohol can be attributed to catalysis of proton transfer from methanol to the HFA− ligand through the chain of hydrogen bonds in 6-membered cyclic structures.
