A short route for the preparation of tetradentate amine-thioether and amine-thiolate ligands derived from thiosalen is reported. The ligating properties of several of the synthesized ligands towards Ni(II) has been examined. The diamine-dithiophenolate ligands (L6)2− [H2L6 = N,N′-dimethyl-N,N;-di(2- mercaptobenzyl)-ethane-1,2-diamine] and (L7)2− [H2L7 = N,N′-di(2-mercaptobenzyl)-piperazine] support
报道了一种用于制备从硫柳氮衍生的四齿胺-硫醚和胺-硫醇盐配体的短途路线。已经检查了几种合成配体对 Ni(II) 的连接特性。二胺-二苯硫酚配体 (L6)2− [H2L6 = N,N'-二甲基-N,N;-di(2-mercaptobenzyl)-ethane-1,2-diamine] 和 (L7)2− [H2L7 = N ,N'-di(2-mercaptobenzyl)-piperazine]支持四配位 NiIIN2S2 配合物 [NiII(L6)] (10) 和 [NiII(L7)] (11) 的形成。相比之下,胺硫醚 2 [N',N"-bis(2-(tert-butylthio)benzyl)ethane-1,2-diamine], L2 [8,11- diaza-5,13-dibenzo-1 ,4-二硫杂环十四烷]及其 N-甲基化衍生物 L2,Me 被发现产生六配位 Ni(II) 配合物
