N‐alkyl hydroxylamines are effective reagents for the amination of organoboronic acids in the presence of trichloroacetonitrile. This amination reaction proceeds rapidly at roomtemperature and in the absence of added metal or base, it tolerates a remarkable range of functional groups, and it can be used in the late‐stage assembly of two complex units.

exhibit potent reduction abilities required for reducing inert substrates, and more new systems with extreme reduction potentials are highly desirable. Notably, developing a new photoredox system usually requires iterative work on molecular design and synthesis. In this work, we present a conceptually distinct modular photoredox system, which features the in situ formation of a photoredox-active species
