A Mild and Efficient Synthesis of 3-Hetarylamino-s-Tetrazines
摘要:
3,6-Bis(3,5-dimethylpyrazol-1-yl)-s-tetrazine reacts with weakly based hetarylamines such as aminofurazans, aminoimidazoles, aminotriazoles, aminotetrazoles, or aminotetrazines on heating in MeCN in the presence of M2CO3 (M = K, Cs) to afford 3-hetarylamino-s-tetrazines, the products of 3,5-dimethylpyrazolyl group displacement.
