Vanadium-substituted polyoxomolybdate

Also, the vanadium-substituted polyoxomolybdate, Q5[PV2Moio04o] (see Figure 9.1b, Q = (C4Hg)4N ) was catalytically active and highly selective in the oxidation of primary and secondary alcohols with nitrous oxide to yield aldehydes and ketones, respectively. Scheme 9.3 [25]. In addition, the same catalyst under similar conditions catalyzed the oxidation of alkylarenes. Scheme 9.3. In the oxidation of alkylarenes with hydrogen atoms at P positions, the substrate is dehydrogenated, for example, cumene to a-methylstyrene, whereas in the absence of p hydrogen atoms ketones are formed, for example, diphenylmethane to benzophenone.
