Alkylation of phenol with camphene in the presence of heteropolyacids supported on metal oxides
摘要:
Alkylation of phenol with camphene in the presence of supported heteropolyacids is studied. The main reaction products are found to be phenyl isobornyl ether, 2-isobornylphenol and 2-isocamphylphenol, the ratio between them being determined by the nature of heteropolyacid and carrier (ZrO2 or TiO2).

Alkylation of 1-naphthol with camphene in the presence of aluminum phenoxide gives 2-isocamphyl-1-naphthol as a major product, while in the case of aluminum isopropoxide 2-isobornyl-1-naphthol is mainly formed and the content of 4-terpenyl-1-naphthols increases.

The alkylation of phenol by β-pinene using Al(OPh)3 as a catalyst was studied. It was found that the composition of the products depended on the ratio of starting materials. The principal products were chromane-type ethers with an equimolar ratio of starting materials and an excess of phenol. ortho-Alkylated phenol and an ether with a terpene substituent of bornyl structure were formed with a two-fold
