The syntheses of the ligand BOPTA, (4-carboxy-5,8,1 l-tris(carboxymethyl)-l-pheny1-2-oxa-5,8,1 l-triazatridecan13-oic acid; benic acid) and its Gd(III), La(III), and Lu(1U) complexes are reported.… Expand
Oxidation of diols with alkali hypochlorites catalyzed by oxammonium salts under two-phase conditions
Preclinical profile and clinical potential of gadocoletic acid trisodium salt (B22956/1), a new intravascular contrast medium for MRI.
Mild Conversion of Primary Carboxamides into Carboxylic Esters.
Lipophilic cage ligands containing two tightly connected 1,7-dioxa-4,10-diazacyclododecane rings: synthesis and X-ray structure of a sodium perchlorate complex
Sodium perchlorate complexes of lipophilic macrotricyclic receptors were obtained in high yield by following a synthetic route in which sodium cation acts as the templating agent in the last step.… Expand
Mild conversion of primary carboxamides into carboxylic esters
Abstract Primary carboxamides are converted into the corresponding alkyl carboxylates by treatment with dimethylformamide dimethylacetal in the appropriate alcohol at 25–45 °C. Yields are very good… Expand
Tailed MnIII-tetraarylporphyrins bearing an axial ligand and/or a carboxylic group: self-consistent catalysts for H2O2 or NaOCl alkene epoxidation
MnIII tetraarylporphyrins bearing either a heterocyclic nitrogen base axial ligand or a carboxylic acid group, or both, covalently bonded to the porphyrin through a single flexible chain, have been… Expand
