Organicazides were prepared fromprimaryamines in high yields by a metal free diazo-transfer reaction using 2-azido-1,3-dimethylimidazoliniumhexafluorophosphate (ADMP), which is safe and stable crystalline. The choice of base was important in the diazo-transfer reaction. In general, 4-(N,N-dimethyl)aminopyridine (DMAP) was efficient, but a stronger base such as alkylamine or DBU was more appropriate
