Synthesis, spectral and structural characterization of cobalt(III) dithiocarbamato complexes: Catalytic application for the solvent free enamination reaction
چکیده انگلیسی
Three new cobalt(III) complexes, [Co(mpcdt)3] (1), [Co(ppcdt)3] (2) and [Co(mppcdt)3]·0.25CHCl3 (3), of 4-methyl piperazine-1-carbodithioate (mpcdt), 4-phenyl piperazine-1-carbodithioate (ppcdt) and 4-(2-methoxyphenyl) piperazine-1-carbodithioate (mppcdt) have been synthesized and characterized by various physicochemical techniques. The catalytic properties of the above complexes have also been examined. A series of β-enaminoesters and β-enaminones were obtained by the reactions of β-ketoesters and 1,3-diketones with aliphatic and aromatic amines, using the above cobalt(III) complexes as catalysts, which have been characterized by NMR, GC-MS and X-ray crystallography. Thermogravimetric analysis of complexes 1 and 2 have been investigated by TG-DTA, which indicate that cobalt sulfide is formed as the final product.91
