Methylenebisanilines and methylenebis(N,N-dialkylaniline)s are prepared by the reactions of 1-hydroxymethylbenzotriazole with anilines and with N,N-dialkylanilines under acidic conditions. Isolation of the intermediate 4-(benzotriazol-1-ylmethyl)anilines and the N,N-dialkyl analogues and their reactions with anilines allow the efficient preparation of both symmetrical and unsymmetrical members of both product classes.
亚甲基双苯胺和亚甲基双(N,N-二烷基苯胺)是由 1-羟甲基苯并三唑与苯胺和 N,N-二烷基苯胺在酸性条件下反应制备的。通过分离中间体 4-(苯并三唑-1-基甲基)苯胺和 N,N-二烷基类似物以及它们与苯胺的反应,可以有效地制备这两类产品的对称和不对称成员。
