Organometallic compounds : XXVI. Ferrocenophane-7-carbocations and their rearrangement
摘要:
The PMR spectra of 7-s-hydroxyl derivatives of [4]ferrocenophanes (I- IV, X) in trifluoroacetic acid (TFA) indicated formation of stable 7-carbocations (XIX), and the starting alcohols were recovered by treatment of the TFA solutions with aq. Na2 CO3. On the other hand, the PMR spectral patterns of [4]ferrocenophane-6-carbocations (XX) appeared in the TFA solutions of 7-t-hydroxyl derivatives (V–IX), and quenching the species gave the corresponding 6-ols (XIII–XVII), rearrangement products.
