3-Diazopyrazolo[3,4-c]pyridazine was synthesized and its transformations were investigated. With reactive methylene compounds the corresponding hydrazones and condensed 1,2,4-triazines were formed. With aromatic amines and naphthols the diazo compound was converted into arylazo derivatives. The diazo compound underwent cycloaddition, reacting as a 1,4-dipole to yield cycloaddition products.
合成了3-二唑并[3,4-c]哒嗪并对其转化进行了研究。与反应性亚甲基化合物形成相应的腙和缩合的 1,2,4-三嗪。使用芳香胺和萘酚,重氮化合物被转化为芳偶氮衍生物。重氮化合物进行环加成反应,以 1,4-偶极子的形式反应生成环加成产物。
