Rapid Synthesis of 1‐Aryl‐3, 3‐dimethyltriazenes by Using In Situ Generated Aryldiazonium Tetrafluoroborate Salts with “DMF‐DMA” under Ambient Conditions

Abstract An efficient and rapid method of synthesizing 1–3,3‐dimethyl triazenes has been developed. This method involves utilizing in situ generated aryldiazonium tetrafluoroborate salts using substituted aryl amines with “DMF‐DMA” (N,N‐Dimethylformamide‐dimethyl acetal) at room temperature. This reaction achieved good to excellent yields (68–95 %) under ambient conditions with a significantly faster rate. The proposed reaction was screened with various withdrawing, donating, and neutral groups containing aryldiazonium salts, and obtained products were confirmed by 1 H, 13 C NMR and mass spectroscopy techniques.
