It is well known that induction of DMN-dI activity could lead to the production of more reactive carbonium ions that alkylate DNA and other macromolecules [23, 24].
Increasing temperature could improve both of the diffusion velocity of carbonium ions (+C[H.
The resulting sulfo conjugate is supposed to be very unstable and can decompose to a reactive DNA-binding carbonium ion.
The rodent bioassay data indicate that methyl eugenol, along with some structural analogs and when administered at high-bolus doses, may cause a shift in metabolism, resulting in the formation of a reactive carbonium ion intermediate.
At acidic centres on catalyst surface, C4 alkenes are easy to form carbonium ions, through which reactions can take place, and consequently, the conversion is high.

Butler and Hussain (1981) suggested a mechanism for the generation of this intermediate and its subsequent oxidation to form a coloured carbonium ion [XII], which has since been cited in reviews on the determination of urea (Taylor and Vadgama 1992; Francis et al.
