De Smet, Gilles published the artcileSelective Nickel-Catalyzed Hydrodeacetoxylation of Aryl Acetates, Application In Synthesis of 645-56-7, the publication is Angewandte Chemie, International Edition, database is CAplus and MEDLINE.
Ni-catalyzed hydrodeacetoxylation of aryl acetates (Ar-OAc) with HBpin in a green carbonate solvent selectively delivered the corresponding deoxygenated arenes (ArH). The method was also applicable to highly challenging guaiacyl and syringyl acetates, leaving -OMe groups intact without arene reduction Renewable 4-propylguaiacol obtained from pine could also be transformed without significant loss in yield vs. oil derived feedstock. The observed chemoselectivity for Ar-OAc vs. ArO-Ac bond cleavage was rationalized based on mechanistic experiments and DFT calculations ArOH side-product formation was attributed to direct competitive Ni-catalyzed reduction of the C=O bond. Hydrodeacyloxylation of a set of aryl alkanoates featured interesting chemoselectivity with a dramatic influence of the length and structure of the alkyl chain on catalysis.
