-
Paragraph 0025; 0041, (2021/04/14)
The invention discloses a method for synthesizing aryl benzyl ether compounds, which comprises the following steps: by using an iron (III) complex containing 1, 3-di-tert-butyl imidazole cations and having a molecular formula of [(tBuNCH = CHNtBu) CH] [FeBr4] as a catalyst and di-tert-butyl peroxide as an oxidant, carrying out oxidative coupling reaction on phenolic compounds and toluene compounds to synthesize the corresponding aryl benzyl ether compounds. The method is the first example for preparing the aryl benzyl ether compound through the oxidative coupling reaction of the phenolic compound and the toluene compound, which is realized by an iron-based catalyst, and has the advantages of atom economy, environmental friendliness and good substrate applicability.

A polymer-bound organocatalyst for Baeyer-Villiger reaction and phenol oxidation under continuous flow conditions is described for the first time.BARhas revealed two catalytic activities that enabled the generation of a novel approach for the synthesis of benzoquinones from β-O-4 lignin models in a one-pot protocol. High catalytic activities (yields up to 98%), selectivities, recyclability and productivity were achieved.

The present report outlines our efforts toward a simple yet elegant protocol for O-acylation of a wide variety of phenols. This highly enabling and solventless method relies on vinyl acetate as an innocuous acyl donor and DABCO as an organocatalyst. Operational simplicity, excellent yields, higher and faster conversion rates without excess reagents, a simple workup and essentially no need of columns are some of the salient features of the reported protocol.
