Metal Ion Complexes of Aromatic Amino Acids Ii
This study has indicated that substitution on the nitrogen atom in aminobenzoic acid markedly decreases complex forming ability; this is especially true in the case of bulky electrophilic groups such as phenyl and acetyl. In these cases, the usual evidence accepted for the formation of coordi nation complexes was not present, and it was therefore concluded that only salts were formed from liga...
متن کاملMetal Ion Complexes of p-Toluenesulfonyl Amino Acids
The methods of polarographic analysis have been applied to the study of dilute aqueous solutions of various divalent transition metal cations coordinated to p-toluenesulfonyl glycine. Metal cations used were cadmium (II), copper (II), lead (II), mercury (II), manganese (II) and zinc (II). Six new and previously unreported compounds were prepared and studied polarographically, and their dissocia...

هدف از این مطالعه طراحی یک روش کلی برای سنتز یک سری از کمپلکس های دو هسته ای متقارن سیکلومتاله شده پلاتین (ii) بوده که دارای یک لیگاند پل زن(1,2-bis[bis(pentafluoro-phenyl)phosphino]ethane),dfppe, است. از واکنش cis-[pt(r)2(sme2)2]، که در آنr= para-tolyl ، با یک اکی والان از لیگاند benzo[h]quinoline,bhq، در استون محصول [pt(r)(bhq)(sme2)] که در آن r= para-tolyl بدست می آید. همچنین از واکنش 5/0 اک...
BIVPLENT METAL COMPLEXES OF SODIUM ASCORBATE
The mode of coordination of8 manganese(fI), cobaltm, nickel(H), copper(II), zinc(H), lead(II) and cadmium(I1) to sodium ascorbate (NaHAsc) was investigated using IR, UV-visible, AAS, elemental microanalyzer, conductivity, magnetic and 'M and I3C NMR spectroscopic studies, NaNAsc is bidentate and coordination was through the carbonyl group and the oxygen atom of carbon-2 enolic hydfoxyl grou...
متن کاملImprovement in 13C NMR Measurements of Ring-Substituted i^-Cyclopentadienyl Metal Complexes
z l.5 Time-consuming 13C N M R measurements o f sparingly soluble ring-substituted cyclopentadienyl metal complexes can be avoided if INEPT techniques are applied. In particular, polarization transfer based on long range 13C -'H couplings (V (13C 1H); n = 2, 3) can be used to observe 13C N M R signals o f quaternary ,3C nuclei, which are difficult to observe in normal 13C N M R spectra. The imp...
