报道了环丙烯(1，4，8，11-四氮杂环十四烷)负载的不对称CoIII-双炔基配合物的合成和表征。在Et3N存在下，[Co(Cyclam)Cl2]Cl与HC2NAPR反应合成了一系列反式-[Co(Cyclam)(C2NAPR)Cl]Cl，其中含R的N-R-1，8-萘酰亚胺为甲苯基(MES，1a)、甲基(Me，1b)、1-乙基丙基(Pen，1c)、2-乙基己基(2-乙基己基，1d)、正辛基(OCT，1e)。化合物1a和1b在NCCH3中分别与AgOTf反应得到intrans‐[Co(cyclam)(C2NAPR)(NCCH3)](OTf)2(2aand2b，)，而在相同条件下与1c、1d和1e反应只产生难处理的混合物。更易溶的2在Et3N存在下与HC2Ar进一步反应生成反式-[Co(Cyam)(C2NAPR)(C2Ar)](OTf)，其中Ar为C6H4-4-NMe2(3a)、NAPMes(3b)和Ph(3c)。用X-射线衍射法(1a，1and3b)、IR、1H核磁共振、UV/Vis和荧光光谱、循环伏安等方法对所有新化合物进行了表征。
The synthesis and characterization of dissymmetric CoIII‐bis‐alkynyl complexes supported by cyclam (1,4,8,11‐tetraazacyclotetradecane) are reported. A series oftrans‐[Co(cyclam)(C2NAPR)Cl]Cl were prepared from the reaction between [Co(cyclam)Cl2]Cl and HC2NAPRin the presence of Et3N, where NAPRisN‐R‐1,8‐naphthalimide with R as mesityl (Mes,1a), methyl (Me,1b), 1‐ethylpropyl (Pen,1c), 2‐ethylhexyl (2‐ethhex,1d), orn‐octyl (Oct,1e). Treating compounds1aand1bwith AgOTf in NCCH3resulted intrans‐[Co(cyclam)(C2NAPR)(NCCH3)](OTf)2(2aand2b, respectively), while reactions with1c,1dand1eunder the same conditions yielded only intractable mixtures. More soluble2areacted further with HC2Ar in the presence of Et3N to affordtrans‐[Co(cyclam)(C2NAPR)(C2Ar)](OTf) with Ar as C6H4‐4‐NMe2(3a), NAPMes(3b) and Ph (3c). All new complexes were characterized using X‐ray diffraction (1a,1cand3b), IR,1H NMR, UV/Vis and fluorescent spectroscopy, and cyclic voltammetry.
