The present invention also relates to a method for synthesising ammonia enriched in nitrogen-15. The invention also concerns certain diazirines of formula (I) likely to be obtained by the claimed synthesis method, and also refers to the 15 N 2 -diazirines of formula (I′). The claimed diazirines can be used in photoaffinity labelling. The 15 N 2 -diazirines can also be used in hyperpolarisation, in particular in the medical imaging field.

In All Cases, An Inexpensive Commercial Solution Of Ammonia (Nh3) In Methanol (Meoh) Was Employed, Avoiding The Difficult Use Of Liquid Ammonia. With Aliphatic Ketones, T-Butyl Hypochlorite (T-Buocl) Was Found To Be The Best Oxidant Whereas It Is Preferable
