9′-spirobifluorene were obtained and characterized by NMR spectroscopy, mass spectrometry, IR spectroscopy, and X-ray diffraction analysis when possible. The formation of a Schiff base to give complexes with the formula [MCp*Cl(2′-CH=NR-2-py-SBF)] (M = Ir, Rh; R = alkyl or aryl (10–12)), through condensation of an amine, and the aldehyde group present in these new complexes was studied leading to a selective
有机胺是存在于多种产品中的重要化合物,这使得开发用于检测有机胺的新系统成为一个有趣的研究领域。新型第 9 族有机金属配合物 [MCp*X(2′-R-2-py-SBF)] (M = Ir, Rh;R = H, X = Cl (6), R = H, X = OAc (7 ), R = CHO, X = Cl (8)), 和 [IrCp*Cl(2', 7-diCHO-2-py-SBF)] (9) (Cp* 五甲基环戊二烯基, SBF = 9,9'-螺二芴)获得了基于 9,9'-螺二芴的双齿 C-N 配体,并通过 NMR 光谱、质谱、红外光谱和 X 射线衍射分析(如果可能)进行了表征。形成席夫碱,得到式 [MCp*Cl(2′-CH=NR-2-py-SBF)] 的络合物(M = Ir、Rh;R = 烷基或芳基 (10–12)),通过胺的缩合,研究了这些新配合物中存在的醛基,从而根据胺和金属中心的性质
