Alkylation of α,Ï-alkanediamines and their N,N′-disubstituted derivatives with 2-(chloromethyl)pyridinium chloride in the presence of hexadecyltrimethylammonium chloride as a phase-transfer catalyst gave conveniently the corresponding N,N,N′,N′-tetrakis (2-pyridylmethyl)-α,Ï-alkanediamines in good yields. N,N′-Bis(2-pyridylmethyl)-N,N′-bis (2-thienylmethyl)-1,2-ethanediamine was similarly obtained.
在十六烷基三甲基氯化铵作为相转移催化剂的存在下,用 2-(氯甲基)氯化吡啶鎓对 δ、Ï-烷二胺及其 N,N′-二取代衍生物进行烷基化反应,可以方便地得到相应的 N,N,N′,N′-四(2-吡啶基甲基)-δ、Ï-烷二胺,收率良好。 同样也得到了 N,N′-双(2-吡啶基甲基)-N,N′-双(2-噻吩基甲基)-1,2-乙二胺。
