Friedel-Craft's alkylation of phenol with 4-hydroxybutan-2-one was studied over Hβ, HY, and Zn2+ and Fe3+ ion exchanged β and Y zeolites. The expected p-alkylated product raspberry ketone [4-(4-hydroxyphenyl)butan-2-one] was obtained regioselectively over Hβ (SiO2/A1203=10) catalyst in 77% yield. The para product was formed by direct alkylation and by the facile rearrangement of O-alkylated product. HY and cation exchanged catalysts yielded O-alkylated, p-alkylated , and small amount of o-alkylated products. This is an abstract of a paper presented at the 13th International Zeolite Conference (Montpellier, France 7/8-13/2001).
