Rapid, efficient methods enable the preparation of phenols from the oxidation of arylhydrosilanes. Electron-rich aromatics benefit from silane activation via oxidation to the methoxysilane using homogeneous or heterogeneous transition metal catalysis. A combination of these two oxidations into a streamlined flow procedure involves minimal processing of reaction intermediates.
