Tetraphenylporphyrin aluminum(iii) salts, TPPAlX, where X = Me, OEt, OiPr, OCHMeCH2Cl, and Cl, and bis(triphenylphosphine)imminium chloride, PPN+Cl- (1 : 1) react with rac-lactide, rac-LA, in neat propylene oxide, PO, to yield chains of enriched isotactic polylactide, PLA, with end groups of PO-Cl and with time these yield cyclic polymers (PO)n(PLA) where n = 2 or 3 and even higher. There is no...

The biomimetic oxidation of etodolac, an anti-inflammatory drug (1) with iodosylbenzene catalyzed by 5,10,15,20-tetraarylporphyrinatoiron(III) chlorides TAPFe(III)Cl (7a-e) in dichloromethane gives 4-hydroxyetodolac (6) and 4-oxoetodolac (5) regioselectively in moderate yields.

In the title compound, [CoCl(C(2)H(8)N(2))(2)(C(7)H(9)N)]Cl(2)·0.5H(2)O, there are two crystallographically independent cations and anions and one water mol-ecule in the asymmetric unit. Both Co(III) ions are bonded to two chelating ethylenediamine ligands, one benzylamine molecule and one chloride ion. The crystal packing is through N-H⋯O, N-H⋯Cl and O-H⋯Cl inter-actions.

The biomimetic reduction of anti-inflammatory drug, nimesulide (1) with sodium borohydride catalyzed by 5,10,15,20-tetraarylporphyrinatoiron(III) chlorides [TAPFe(III)Cl] has been studied in organic solvents under anaerobic and aerobic conditions.

In the title compound, (C(12)H(11)N(3))[SbCl(5)]·H(2)O, the Sb(III) centre is surrounded by five Cl atoms and displays a distorted square-pyramidal coordination geometry. The dihedral angle formed by the plane of the imidazole ring system with the pyridine ring is 4.380 (15)°. The crystal structure is stabilized by N-H⋯Cl, O-H⋯Cl and N-H⋯O hydrogen bonds, forming a three-dimensional network.

In the title compound, [CoCl(CH5N)(C3H10N2)2]Cl2·H2O, the Co(III) ion has an octa-hedral coordination environment and is surrounded by four N atoms of two propane-1,3-diamine ligands in the equatorial plane, with another N atom of the methylamine ligand and a Cl atom occupying the axial positions. The crystal packing is stabilized by inter-molecular N-H⋯O, N-H⋯Cl, and O-H⋯Cl inter-actions, gene...

In the title compound, [Cr(C(2)H(6)OS)(6)]Cl(3), each Cr(III) ion is located on a three-fold inversion axis and is coordinated by six dimethyl-sulfoxide ligands [Cr-O = 1.970 (2)-1.972 (2) Å; O-Cr-O = 88.19 (9) and 91.81 (9)°] in a slightly distorted octa-hedral geometry. The Cl(-) anions take part in the formation of weak C-H⋯Cl hydrogen bonds, which contribute to the crystal packing stabiliza...

Green rust compounds (GR), i.e., Fe(II-III) layered double hydroxides, are important transient resulting from the corrosion of steel in seawater. The sulfated variety, GR(SO42?), was reported as one main components product layer, while chloride GR(Cl?), more rarely observed. carbonate GR(CO32?), is favored by an increase pH and forms preferentially cathodic areas metal surface. Since Mg(II) abu...
