Silica supported molybdenum(VI) oxide (20%) has been explored as a new solid catalyst for the Beckmann rearrangement and the results are compared in parallel with the known β-zeolite as a catalyst for the same transformation. Both catalysts were found to facilitate the rearrangement under mild conditions and the conditions employed were tolerable for protecting groups such as isopropylidene, cyclohexylidene
