Crystals of the title compound, [Fe(C(8)H(7)N(3))(3)](2)[PMo(12)O(40)]·6H(2)O, prepared under hydro-thermal conditions, are isotypic with the Mn(2+) and Cd(2+) analogues. The Fe(2+) cation is in a distorted octa-hedral coordination by six N atoms from three chelating 3-(2-pyrid-yl)-1H-pyrazole ligands. The heteropoly-anion [PMo(12)O(40)](4-) is a one-electron reduced species in which two O atom...

A series of Keggin-type heteropoly compounds (HPC) having different countercations (Co, Fe) and different addenda atoms (W, Mo) were synthesized and characterized by means of Fourier-Transform Infrared Spectrometer (FT-IR) and X-ray powder diffraction (XRD). The catalytic properties of the prepared catalysts for the dimethyl carbonate (DMC) synthesis from CO(2) and CH(3)OH were investigated. Th...

β -Acetamido ketones are valuable building blocks for the preparation of β -amino ketones or β -amino alcohols such as the antibiotic nikkomycins [1] and neopolyoxines [2]. α-Acetamido ketones are obtained in the Dakin-West reaction [3] and β -acetamido ketones by the Iqbal route. In the latter, an aromatic aldehyde, an enolizable ketone and acetonitrile are condensed in the presence of acetyl ...
