An examination by 15N NMR of Na15NO2 under various conditions of acidity led to the identification of several electrophilic nitrogen species.This permitted the selection of reaction conditions of low acidity which favor nitrosation at the nitrogen atom of thioureas rather than on the normally more reactive sulfur, leading to the isolation of novel N-nitrosothioureas.In contrast it was shown by employing 15N and 13C labeling that higher acidity conditions favor reaction via a detectable thionitrosyl intermediate.
