Formation of stable alkenyl carbenium ions in high yield by adsorption of 1-methylcyclopentene on zeolite Y at low temperature.
The formation of dimerized alkenyl carbenium ions, characterized by an IR band at 1513 cm-1 and a UV band at 323 nm, was observed by adsorption of 1-methylcyclopentene on HY and DY zeolites at temperatures as low as 150 K.
