The rearrangement reaction of benzyl aryl ether catalyzed by polyphosphoric acid (PPA) was systematically investigated. Optimal structural tuning of substitutions of electron withdrawing group (EWG) and electron donating group (EDG) at phenolic moiety or benzyl moiety benefits the rearrangement and the regioselectivity of the rearrangement obeyed the substitution directing rule at the aromatic ring. This readily available rearrangement method is of practical interest for the benzylation of diverse aromatic phenols. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Application of 103-16-2).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Application of 103-16-2
