In the gas-phase attack of t-C4H9+ ions, obtained in the dilute gas state from the radiolysis of neopentane, on phenol and anisole, the competition between n-type and π-type nucleophilic centres of the ambident substrates is strongly biased in favour of the oxygen atom, leading to the predominant formation of the t-butylated oxonium ions as the major reaction intermediates.

Abstract
In the gas-phase attack of t-C4H9+ ions, obtained in the dilute gas state from the radiolysis of neopentane, on phenol and anisole, the competition between n-type and π-type nucleophilic centres of the ambident substrates is strongly biased in favour of the oxygen atom, leading to the predominant formation of the t-butylated oxonium ions as the major reaction intermediates.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
