The sequel to a carbocyclic nucleoside synthesis: a divergent access to both arenediazonium ions and aryl triflates
摘要:
Depending on the amount of acid used, treating aryl-dialkyl triazenes of general structure 3 with triflic acid resulted in the formation of either the corresponding arenediazonium triflates 4 or aryl triflates 8 apparently by two different pathways, the latter conversion being favoured at high acid concentration.

scanning calorimetry (DSC)/thermal gravimetric analysis (TGA), we have determined the thermaldecompositionenergies for the number of solid arenediazonium triflates comparing to 4-nitrobenzene tosylate and 4-nitrobenzentetrafluoroborate. The kinetics of thermaldecomposition, activationenergies, and half-lives of the studied diazonium salts (DSs) were found. Using gas chromatography–mass spectrometry

A variety of stable, safe, and soluble arenediazonium triflates ArN2+ TfO– were obtained easily by diazotization of anilines with tert‐butyl nitrite in the presence of triflic acid. They are highly reactive, forming aromatic iodides, azides, and boronic acids, and also undergo an unusual metal‐free chloro‐dediazonization with chloroform and CCl4.
