In the presence of a catalytic amount of oxovanadium(IV) complexes coordinated by 1,3-diketone-type ligands, benzene and its analogues are directly oxygenated into phenols by combined use of molecular oxygen and crotonaldehyde at room temperature.

The invention discloses a preparation method of m-tert-butylphenol. The preparation method comprises the following steps: with tert-butylbenzene as a raw material, nitrifying tert-butylbenzene to obtain 2,4-dinitro-tert-butylbenzene, then conducting reduction and Baberger rearrangement to obtain 2,4-diamino-3-hydroxy tert-butylbenzene, and finally, performing diazotizing and reducing to remove amino groups so as to obtain m-tert-butylphenol. According to a process route in the invention, para-isomer generation is effectively avoided, and m-tert-butylphenol with a purity of 99% or above can beobtained through simple distillation; and the method has the advantages that raw materials are cheap and easy to obtain, the process is simple and has few side reactions, and the method is suitable for industrial production.

Substituted phenols are requisite molecules for human health, agriculture, and diverse synthetic materials. We report a chemical synthesis of phenols, including penta-substituted phenols, that accommodates programmable substitution at any position. This method uses a one-step conversion of readily available hydroxypyrone and nitroalkene starting materials to give phenols with complete regiochemical control and in high chemical yield. Additionally, the phenols can be converted into highly and even fully substituted benzenes.
