Mix and match : A tungsten–tin mixed hydroxide (W–Sn hydroxide), prepared by the simple coprecipitation method, acts as a reusable heterogeneous catalyst for the dehydration of various aldoximes to the corresponding nitriles (see scheme, top). Furthermore, the W–Sn hydroxide catalyst could be applied to the direct one‐pot synthesis of nitriles from hydroxylamine and the corresponding aldehydes (see scheme, bottom).
