Synthesis of Catechols from Phenols via Pd-Catalyzed Silanol-Directed C–H Oxygenation

A silanol-directed, Pd-catalyzed C–H oxygenation of phenols into catechols is presented. This method is highly site selective and general, as it allows for oxygenation of not only electron-neutral but also electron-poor phenols. This me...

Models for biomedical interfaces: a computational study of quinone-functionalized amorphous silica surface features

A density functional theory (PBE functional) investigation is carried out, in which a model of an amorphous silica surface is functionalized by ortho-benzoquinone. Surface functionalization with catechol and quinone-based compounds is re...
