Nitromethane as a nitrogen donor in Schmidt-type formation of amides and nitriles
Science, 2019 Sourcing nitrogen from nitromethane Nitromethane is produced in bulk quantities for use as a solvent. Its applications as a reagent have focused mainly on the acidity of the methyl protons en route to modifying the carbon center. Liu et al. now report an

Delayed catalyst function enables direct enantioselective conversion of nitriles to NH2-amines
Science, 2019 Amines emerge, as copper bides its time Concurrent operation of two or more catalytic cycles requires a delicate balance of relative rates. Zhang et al. developed an amine synthesis in which allenes and nitriles are coupled under reductive conditions.

Sustainable Alkylation of Nitriles with Alcohols by Manganese Catalysis.
Journal of Organic Chemistry, 2019 A general and chemoselective catalytic alkylation of nitriles using a homogeneous nonprecious manganese catalyst is presented. This alkylation reaction uses naturally abundant alcohols and readily available nitriles as coupling partners.
