Abstract Bis[bis(dibutylamino)methylen]hydrazine 8 is prepared from N,N,N′,N′-tetrabutylchloroformamidinium chloride (4c) and hydrazine. Bromine transforms 8 to the heterocyclic guanidinium salt 15a which is isolated as tetraphenylborate. From N,N,N′,N′-tetraalkylchloroformamidiniumchlorides and ethylendiamine the diguanidines are prepared which are alkylated to give diguanidinium salts, From these salts guanidinium salts can be prepared by anion metathesis with tetraphenylborate-, iodide-, hexafluorphosphate-, trifluoromethansulfonat-, bis(trifluormethansulfonyl)imide and tricyanmethanide as counteranions. The structure of the compounds 15 and 17b is confirmed by crystal structure analyses.

摘要 双[双(二丁基氨基)亚甲基]肼 8 由 N,N,N',N'-四丁基氯甲脒氯化物 (4c) 和肼制备而成。溴将 8 转化为杂环胍盐 15a，以四苯基硼酸盐的形式分离。由 N,N,N',N'-四烷基氯甲脒氯化物和乙二胺制备二胍，将其烷基化得到二胍盐，从这些盐中可以通过阴离子复分解与四苯基硼酸盐-、碘化物-、六氟磷酸盐-、三氟甲磺酸盐-，双（三氟甲磺酰基）亚胺和三氰甲胺作为抗衡阴离子。化合物15和17b的结构由晶体结构分析证实。
