Using an immobilized nitrilase from Rhodococcus sp. mild and selective hydrolysis of nitriles can be achieved even in the presence of acid or base sensitive groups under neutral conditions. This method is applicable to a broad range of substrates as exemplified by aliphatic, alicyclic, heterocyclic and carbohydrate type nitriles.

A highly efficient electrocatalytic 1,2-dioxygenation of alkenes utilizing readily available materials in ambient conditions is developed. The protocol is widely applicable to aliphatic and aromatic alkenes with excellent faradaic efficiencies and yields of up to 96 %. The versatility of the method is expanded with alkenoic acids towards lactone derivatives and with other carboxylic acids like HCOOH
