Iminyl is a term used in organic chemistry for an unstable radical that contains either an N=C-R or C=N-R group. There are several synonyms for this term used in different contexts. For example, in the biochemistry field, iminyl is often referred to as an imine radical or iminylnitrene. In organic synthesis, alternative terms include azavinyl and azavinylene, while in polymer chemistry, iminyl radicals are sometimes referred to as iminoalkyl radicals. Regardless of the exact terminology used, these reactive intermediates hold a significant place in the study of organic chemistry and are important for understanding many chemical reactions.
