Ferrous perchlorate

Finally, in a recent study by Walling and El-Taliawi (216) it was shown that solvolytically generated vinyl cations may be reduced by Fe ions in solution to the corresponding vinyl radical. When 2-buten-2-yl triflate was solvolyzed in concentrated ferrous perchlorate solution in the presence of acrylonitrile monomer, polymerization of the acrylonitrile was observed. No such polymerization occurred under identical conditions in the absence of Fe ions. It seems that the polymerization of acrylonitrile was initiated by the vinyl radicals formed by reduction of the intermediate vinyl cation by Fe as follows (216) ... 

D. Dolphin Groves and his co-workers 9 have shown that ferrous perchlorate and hydrogen peroxide can carry out hydroxy-lations which bear close parallels to the P-450 mediated systems.

An interesting alternative to the use of chromium(VI) oxidants for the conversion of 1 to 2 involves the use of a low-valent iron reagent prepared in situ by the action of hydrogen peroxide on an iron(II) complex of 1 (73). Vinblastine (as the free base) is treated with 2 equiv of perchloric acid in acetonitrile at -20°C. Ferrous perchlorate is then added, followed by the addition of excess 30% hydrogen peroxide. Work-up of the reaction mixture with a saturated solution of ammonium hydroxide gives 2 in yields of 35-50% after chromatography.

Complexes in which L is a substituted pyridine have been prepared by reducing the corresponding pyridine adducts of diperoxychromium(vi) with acidic ferrous perchlorate followed by the usual ion-exchange separation. Acid aquation of these complexes involves terms in A i and A [equation (27)]. The recent rate data are collected in Table 12 log Aq and log A i vary linearly with the pK of the pyridines.
