AbstractPalladium and platinum complexes of the rhodaninato ion and 3‐substituted rhodanines have been prepared. From infrared spectra in the 4000‐200 cm−1region and nuclear magnetic resonance data it is concluded that for the compounds ML2X2(where X = Cl, Br, I and L = 3‐substituted rhodanine) the metal is bondedviathe thiocarbonyl group of the ligand. The assignment of the M‐X and M‐S stretching vibrations is given and discussed. In the compounds ML2(where L is the rhodaninato ion) the rhodanine is complexed as monobasic anion. For these complexes we suggest a polymeric structure in which the coordination takes place through the nitrogen and the thiocarbonyl group of

AbstractFrom the 220 Mc/s NMR spectra of 2‐p‐chlorophenyl‐1,3‐dioxane (I), 2‐phenyl‐1,3‐oxathiane (II) and ‐dithiane (III), trimethylene sulfite (IV) and 2‐oxo‐2‐phenoxy‐1,3,2‐dioxaphosphorinane (V) the spin‐spin splitting pattern of the ‐CH2‐CH2‐CH2‐ fragment of the ring is analyzed. The various types of coupling constants (geminal, vi

摘要:

AbstractFor six‐membered ring compounds having a −CH2‐CH2‐ fragment for which four vicinal coupling constants follow from the NMR spectrum (ABCD type), the ratio R = (Jtrans+J′trans/(Jcis+J′cisis equated to the ring torsional angle ψ in that fragment. The ψ values calculated from experimental coupling constants oftrans‐2,3‐dichloro‐1,4‐dioxane (I) and ‐oxathiane (II), 2‐p‐chlorophenyl‐1,3‐dioxane (III), 2‐phenyl‐1,3‐dithiane (IV), trimethylene sulfite (V) and 2‐oxo‐2‐phenoxy‐1,3,2‐dioxaphosphorinane (VI) show an excellent agreement with the corresponding torsio

摘要:

AbstractSeven new complexes are reported with nitrobenzene as the ligand,viz.[M(C6H5NO2)6]2+[SbCl6]2−with M is Mg(II), Ca(II), Mn(II), Fe(II), Co(II), Ni(II), and Zn(II).No shift in the NO stretching frequencies has been observed. The NO2out of plane bending vibration shifts to higher frequencies dependent on the metal ions.Investigation of ligand field spectra indicates the presence of octahedral species M(nitrobenzene)62+in the solid compounds. Values for Dq and B for the Co and Ni compounds are reporte

摘要:

AbstractThe insertion of aldehydes and ketones onto the germanium‐nitrogen bond of trialkylgermylamines leads to α‐aminoalkoxygermanes which are generally not very stable.Their decomposition leads to trialkylgermanium oxides and enamines or imines corresponding to the aminogermanes and carbonyl derivatives.The formation of enamine or imine takes place throughgem‐diamines which are usually unstable. The derivatives obtained by insertion of the halogenated aldehydes and ketones such as chloral and hexachloroacetone decompose through β‐elimination, with formation of trialkyl(trichloromethyl)germane R3GeCCl3, trialkylchlorogermane and dichlo

摘要:

AbstractThe27Al magnetic resonance was studied in benzene and toluene solutions containing AlX3(X = Cl, Br) (0.2−0.25M) and PR3(R = C2H5, C6H5) in molar ratios varying from 1: 1 to 1: 16. In the solutions containing P(C6H5)3the adducts (C6H5)3PAlX3were found to be the only Al‐containing species present in significant concentrations. In solutions containing P(C2H5)3, adducts (C2H5)3PAlX3and {(C2H5)3P}2AlX3are present; the stability constants of {(C2H5)3P}2AlX3were determined. These results are supported by dielectric measurements, which show the adducts {(C2H5)3P}2AlX3to have small dipole moments, probably due to a trigonal‐bipyramidal structure with the phosphine ligands in the axial posi
