Electrophilic aromatic substitution. Part III. The nitration and acid-catalysed hydrolysis of benzylidyne trifluoride
Abstract
The partial rate factor for the meta-nitration of benzylidyne trifluoride by nitric acid in sulphuric acid is 6·7 × 10–5. Evidence is presented to support a mechanism for the hydrolysis of benzylidyne trifluoride to form benzoic acid in concentrated sulphuric acid which involves a transition state similar in structure to the carbonium ion PhCF2+.
