Bridged ferrocenes. Part 14. A kinetic study of the hydrolysis of [m]ferrocenophan-1-yl acetates
Abstract
[m]Ferrocenophan-1-yl acetates undergo solvolysis in aqueous acetone by an SN1 mechanism, the rates increasing sharply through the series [3]- < FcCH(OAc)Me < [5]- < [4]-. Under these conditions, or in ethanol, [4]ferrocenophan-2-yl acetate is inert.
