tert-Butyl hypochlorite is a versatile and inexpensive oxidizing agent, that allows the conversion of alcohols to ketones, aldehydes to acid chlorides, sulfides to sulfoxides, and hydroxylamines to nitroso compounds. tert-Butyl hypoiodite, which is more reactive, can be prepared from tert-butyl hypochlorite and a metal iodide (M. Ishihara, H. Togo, Synthesis, 2007, 1939. DOI).
Various alcohols were efficiently converted into the corresponding nitriles at room temperature by treatment with tert-butyl hypochlorite, diiodine, or 1,3-diiodo-5,5-dimethylhydantoin (DIH) in the presence of TEMPO, followed by treatment with diiodine and aqueous ammonia. The nitriles were obtained in good yields and high purities by a simple extraction of the reaction mixture with chloroform and subsequent removal of the solvent.

An efficient preparation of 2-imidazolines was achieved from aldehydes and ethylenediamines in the presence of tert-butyl hypochlorite. By this method, 1,3-bis(imidazolin-2-yl)benzene and 2,6-bis(imidazolin-2-yl)pyridine, which act as chiral ligands, could be prepared directly from the corresponding dialdehydes in high yields.
