preparation of the masked thiolate head unit S-(2,6-diformyl-4-methylphenyl) dimethylthiocarbamate 6 is detailed and two new masked thiolate head units, S-(2,6-diformyl-4-tert-butylphenyl) dimethylthiocarbamate 7 and S-(2-formylphenyl) dimethylthiocarbamate 8, are prepared by this method. The synthesis, crystal structure, NMR spectra and electrochemical properties of the first macrocyclic complex to be derived
的一种改进的制备硫醇盐掩蔽头单元小号- (2,6-二甲酰基-4-甲基苯基)二甲基硫代氨基甲酸酯6中详述和两个新的掩蔽硫醇头单元,小号- (2,6-二甲酰基-4-叔丁基苯基)二甲基硫代氨基甲酸酯7和S-(2-甲酰基苯基)二甲基硫代氨基甲酸酯 通过这种方法准备图8。合成,晶体结构,核磁共振谱讨论了由7 [[Ni 2 L1](ClO 4)2衍生的第一大环配合物的电化学性质。氧化作用[Ni 2 L2](CF 3 SO 3)2(L2 2-是由6和1,3-二氨基丙烷)与硝酸铈(IV)铵引起的黑色络合物[Ni 2 L2] [Ce(NO 3)6 ]沉淀,据信其中含有一个镍(III)中心。该配合物在DMF中随时间(约24小时)分解而形成红色二镍(II)配合物[Ni 2 L2](NO 3)2 ·2DMF,其结构已得到表征。氧化作用[Ni 2 L3](CF 3 SO 3)2(L3 2-是由6和1,4-二氨基丁烷)与I
