A catalytic, metal-free intramolecular rearrangement of benzyl phenyl ethers using nitrosonium salt as a catalyst is described. The optimized reaction conditions enabled a catalytic and metal-free Friedel-Crafts alkylation reaction with benzylic alcohols, producing water as the stoichiometric byproduct. A comprehensive scope (>50 examples) for both approaches and application in drug synthesis were demonstrated. Mechanistic studies suggest a Lewis acid-based mechanism for the metal-free Friedel-Crafts reaction.

The invention belongs to the technical field of electronic material intermediate, and discloses a method for synthesizing 4-(4-hydroxyphenyl) cyclohexanone. The method comprises the following steps: reducing 4,4'-diphenol with Al-Ni to prepare 4-(4-cyclohexanamide)-phenol; then preparing 4-(4-benzyloxy-benzene) cyclohexanol with benzyl chloride protection; oxidizing with chromium trioxide to obtain 4-(4-benzyloxy-benzene) cyclohexanone; and finally hydrogenating with 5% Pd/C to obtain 4-(4-hydroxyphenyl) cyclohexanone having a molecular formula of C12H14O2. The 4-(4-hydroxyphenyl) cyclohexanone prepared by the method is an electronic material and medicinal intermediate; and the synthesizing method has the advantages of reasonable process design, high yield and short production cycle, is economical and feasible, and easily realizes industrial production.
