Abstract:
A novel mechanoredox-enabled synthesis of aromatic and aliphatic isothiocyanates from primary amines and carbon disulfide under ball milling conditions using a piezoelectric material (BaTiO3) as the redox catalyst has been developed. This method displays several features, such as short reaction time, operational simplicity, room temperature and air conditions, minimal solvent, broad substrate scope, and recyclable cheap catalyst. Preliminary mechanistic studies revealed that highly polarized piezoelectric material acted as a single-electron transfer (SET) oxidation reagent for the key desulfurization process.

Though catalytic hydrogenation can reduce nitrobenzenes, the reduction is nonselective in the presence of other functional groups. For instance, if nitrobenzene contains an aldehyde group,...
Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
