Interplay of Corrosion and Photocatalysis during Nonaqueous Benzylamine Oxidation on Cadmium Sulfide

The photo(electro)chemical properties of bulk, nanowire, and chemical bath deposits of cadmium sulfide (CdS) for benzylamine oxidation to N-benzylidenebenzylamine (N-BB) in acetonitrile have been evaluated as a model for the activity and stability of CdS toward selective organic oxidations. CdS photocatalysts selectively deliver N-BB at rates ranging from 5 to 26 mM h-1. Although CdS is a capable photocatalyst, SEM imaging and XPS analysis reveal significant morphological and compositional changes to the particles upon photolysis in benzylamine. These surface changes and surface sulfide oxidation are accompanied by Cd2+ leaching and hydrogen sulfide evolution, highlighting both redox and acid-base pathways of nonaqueous CdS corrosion. All facets of corrosion have been linked directly with amine reactivity, as the CdS particles are unaffected by substrate-free photolysis. A series of experiments using N,N-dimethylbenzylamine, 4-N,N-trimethylaniline, and ferrocene show that nonaqueous CdS corrosion is facilitated by acidic reaction intermediates opposed to photogenerated holes. Additionally, water and oxygen are essential components to corrosion, as photoelectrochemistry under dry/air-free conditions displays higher and stable photocurrent density as well as material stability. Finally, CdS nanowires display improved corrosion resistance, suggesting that control of particle morphology and/or electronic structure is essential for developing novel chalcogenide photocatalysts.

In this work, we describe the one-pot synthesis of α-amino nitrile units by the concomitant addition of alkyl (or aryl) Grignard reagents and TMS cyanide through alkylative Strecker cyanation from readily available formamides. The reaction is broad in sco

A novel and effective dual catalysis system, copper combined with pyridoxal phosphate, which is anchored in maghemite nanoparticles were designed and applied to synthesize α-aminonitriles from benzyl alcohols. This catalytic system has the potential ability to perform oxidation reactions and subsequently synthesize alpha-amino nitrile in a reaction environment. Thus, the purpose of this paper is introducing a heterogeneous, sustainable and recyclable catalytic system to perform reactions that require a transition metal catalyst and organocatalyst continuously to achieve a target molecule. The catalysis system is examined and investigated with seven useful analyses such as FT-IR, TGA, VSM, SEM, TEM, XRD, and ICP.
