In this work, novel ferrocene-based ionic liquids, 1-(ferrocenylbutyl)-
4-(3-methylimidazolium) Azide and 1-(ferrocenylbutyl)-4-(3-
methylimidazolium) Tetrafluoroborate, were synthesized and utilized
in the oxidation esterification reaction of aldehydes in the present of
different reagents such as NaN3, (K2CO3 and NCS), (KI and KCN), (I2 and
K2CO3), (KMnO4). The results were compared with that of [BMIM][X]
(X=Cl, BF4) under the same conditions. As expected, ferrocene-based
ionic liquids showed better results; It seems, iron nuclear may play a
similar role such as iron catalysts in these novel ionic liquids and can
facilitated the oxidation esterification reaction with improve the yield
and decrease the reaction time.
