- Synthesis and structural studies of iron (II) and iron(III) sulfonates
-
The iron(II) sulfonates Fe(CF3SO3)2 and Fe(p-CH3C6H4SO3)2 have been prepared and on the basis of vibrational and electronic spectra and magnetic and Moessbauer data have been assigned a layer lattice structure involving hexacoordinated iron(II) and terdentate bridging anions.The FeO6 chromophore in these compounds is distorted by a trigonal elongation along the C3 axis.Fe(CH3SO3)2 has been obtained in two isomeric forms, one having a trigonal elongation of the FeO6 chromophore, the other a trigonal compression.No structural isomerism has been found for the other iron(II) sulfonates; however, evidence for such isomerism in methanesulfonates of cobalt(II) and zinc(II) is presented.While Fe(CF3SO3)2 and Fe(p-CH3C6H4SO3)2 appear to be magnetically dilute the presence of antiferromagnetic coupling in both forms of Fe(CH3SO3)2 is indicated.The iron(III) sulfonates, Fe(CF3SO3)3, Fe(p-CH3C6H4SO3)3, and Fe(CH3SO3)3, have been prepared and all three are magnetically concentrated exhibiting magnetic moments which are significantly less than 5.92 BM and which decrease with decreasing temperature.

- Reaction products of hydroxy aromatic or alkylphenylether compounds and alkenylsuccinic acid, anhydride, or ester
-
Novel products suitable for use as detergents in lubricant compositions are provided. Such products include the reaction products of (1) the product of reaction between an alkenylsuccinic acid, ester or anhydride and a hydroxyaromatic compound, (2) the product of reaction between (1) and an amine selected from the group consisting of an alkanepolyol such as an amino alkanediol and a polyalkylenepolyamine; (3) the reaction product of (2) and an aldehyde; (4) the reaction product of (3) with a metal salt capable of forming a stable complex with amines; (5) the reaction product of (2) with a metal salt; and (6) the product of reaction between an alkenylsuccinic acid or anhydride and an alkyl phenyl ether.
