Calcined and silylated K10 montmorillonites as catalysts of pericyclic reactions of trans-anethole

Cation-exchanged K10 montmorillonites are calcined and silylated in order to eliminate acid sites. The solids obtained promote the Diels-Alder reaction of cyclopentadiene with trans-anethole and the cyclodimerization of trans-anethole.

Anethole isomerization and dimerization induced by acid sites or UV irradiation

The formation of cis-anethole and various dimers as a result of the exposure of trans-anethole to microporous solid acids (dealuminated HY zeolites), or UV-Vis irradiation was established by means of high resolution gas chromatography coupled to mass spectrometry. 3,4-bis-(4-Methoxyphenyl)-(E)-hex- 2-ene was the most abundant compound among eight different methoxyphenyl- disubstituted hexenes produced by electrophilic addition and elimination reactions induced by HY zeolites. (1a,2a,3b,4b)-1,2-bis(4-Methoxyphenyl)-3,4- dimethylcyclobutane was the principal component in the mixture of 5 methoxyphenyl-disubstituted cyclobutanes found, together with cis-anethole, after UV-Vis irradiation of a trans-anethole solution in toluene.
