摘要
王序昆等合成了一系列（Fe（CO）2CP）2Sn—Ar—R三核金属有机化合物。R:—H,—O-CH3,P-CH3,m-CH3;—P-OCH3;—m-Cl,—P-Cl;2,4,6-（CH3）3,2,3,4,5,6-（Cl）5。X:—Sph,—SCN,—SCNMe,—NO2,—NO3,—N3,—Cl,—Br,—I。
A series of Fe-Sn-Fe tri-nuclears organome-tallic compounds have been separated by partition thin-layer chromatography using liquid paraffin as stationary phase.The results show that increasing the electron donating ability of the substituting groups on the aromatic rings will cause the Rtv alues to increase as follows;Rf(OCH3)>Rf(CH3)>Rf(H) Rf((m-CH3)>Rf(P-CH3)>Rf(OCH3) Rf(m-Cl)>Rf(P-Cl)increasing the negative induction effect of the substituted groups on the mtetal Sn also lead the Rf to increase.The λmax values in the B band of Ultra-Violet Spectroscopy change with the same rule as the results obtained by partition thin-layer Chromatography as well
