been identified as versatile aerobicoxidationcatalysts. Primary amines were readily cross-coupled with primary nitroalkanes via deaminative pathway to give nitroalkene derivatives in good to excellent yields. Secondary and tertiary amines were inert to ortho-naphthoquinone catalysts; however, secondary nitroalkanes were readily converted by ortho-naphthoquinone catalysts to the corresponding nitrite

acid‐free N‐nitrosation/nitration of the N−H bonds in secondary amines with Fe(NO3)3 ⋅ 9H2O as the nitroso/nitro source through an electrocatalyzed radical coupling reaction was developed. Cyclic aliphatic amines and N‐heteroaromatic compounds were N‐nitrosated and N‐nitrated, respectively, under mild conditions. Control and competition experiments, as well as kinetic studies, demonstrate that N‐nitrosation

Abstract Bismuth(III) chloride–sodium nitrite was used as a mild and efficient reagent for N-nitrosation of various tetrazoles, secondary amines, and amides under ambient conditions. Nitrosation took place chemoselectively at the nitrogen atom, giving corresponding N-nitroso derivatives in good to excellent yield.
