Jm. Fraile et al., CALCINED AND SILYLATED K10 MONTMORILLONITES AS CATALYSTS OF PERICYCLIC-REACTIONS OF TRANS-ANETHOLE, Chemical communications, (16), 1996, pp. 1981-1982
Cation-exchanged K10 montmorillonites are calcined and silylated in or
der to eliminate acid sites. The solids obtained promote the Diels-Ald
er reaction of cyclopentadiene with trans-anethole and the cyclodimeri
zation of trans-anethole.
