Alkyl/benzyl azides can be readily synthesized in excellent yields from their corresponding alcohols by stirring a solution of sodium azide in DMSO with a thoroughly ground equimolecular mixture of triphenylphosphine, iodine and imidazole.

1,5-H transfersfromcarbon to N-tributyltin substituted nitrogen proceeded smoothly and were much more efficient than 1,5-H transfersfromcarbon to ordinary nitrogen. 1,5-Tribuyltin group transferfromcarbon to nitrogen and intramolecular addition of an aminyl radical to a nirile group were also observed for the first time.
