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
Organicazides were prepared fromprimaryamines in high yields by metal-free diazo transfer with 2-azido-1,3-dimethylimidazoliniumhexafluorophosphate, which is a stable, crystalline solid that is easy to handle.
The reaction of arenediazonium tetrafluoroborates with chlorotrimethylsilane in a tetrahydrofuran/N,N-dimethylformamide (DMF) (5v/3v) solution afforded the protodediazotization products in high yields. The reactions of the diazonium salts with halotrimethylsilanes in DMF were found to give the corresponding haloarenes. Among the halodediazotization reactions, the iododediazotization with iodotrimethylsilane
