• ), specifically by extracting a hydrogen atom from the α-position of benzyl radicals A. The process described above led to the formation of the corresponding olefins 11, eliminating the need for a carbon–iodine bond formation step. Alkylation Diaziridines are highly versatile building blocks in synthesis, with

The most accessible and widely studied precursors for unstable azomethine imines are diaziridines, i.e., three-membered rings containing two nitrogen atoms [15]. Thus, the unstable N,N'-cyclic
