The recoverable heterogeneous silica-supported catalyst selenenamide 2 was prepared by the coupling of 3-aminopropylsilicate (4)with 2-chloroselenobenzoyl chloride (6). Its catalytic activity was demonstrated in tert-butyl hydroperoxide oxidation of aldehydes 8 to carboxylic acids 9 and benzylamines 17 to nitriles 18. Moreover, it was employed for hydrogen peroxide oxidation of azomethine compounds such as tosylhydrazones 10, oximes 13 and N,N-dimethylhydrazones 16 to parent ketones 12, arenecarboxylic acids 11 and 15, their methyl esters 14 and nitriles 18 depending on the substrate used and the reaction conditions. The catalystwas simply recovered by filtration and could be reused.
