摘要：Various uful p-substituted phenol derivatives can be advantageously obtained by reacting a phenol compound with an organic halide lected from the group consisting of haloforms, tetrahalogenocarbons, and substituted or unsubstituted allyl halides in the prence of an alkali metal hydroxide using as catalyst immobilized cyclodextrin cross-linked through its hydroxy groups with a divalent hydrocarbyl group having free valences at both ends, optionally being substituted by a substituent lected from among an alkyl group, a halogen atom, and a hydroxy group, and optionally having at least one lected from the group constituting of an oxygen atom, a sulfur atom, and phenylene between at least part of adjacent carbon atoms. The ud cyclodextrin catalyst can be recovered with ea and no loss, and can be repeatedly ud for this process without reducing the yield and lectivity of the phenol derivative.
