Heavy Metal Removal Using Dithiocarbamates
ajor emphasis is placed today on treating plating solutions and rinsewater to reduce the concentration of toxic metals to below established limits prior to discharge or water reuse. Available technology is adequate for partial treatment of most wastewater; however, new technology is needed to scavenge heavy metals from complexed or chelated compounds in rinsewater. Several report^^-'^ from this...
متن کاملPyrrolidine dithiocarbamates of Pd(II)
The dithioester (CH2)4NCS2CH3 (PyDTM, 1-pyrrolidinecarbodithioate methyl ester) has been prepared by reaction of the parent ammonium salt NH4PyDT ðPyDT 1⁄4 ðCH2Þ4NCS 2 Þ with methyl iodide in water/ethanol. The reaction of PyDTM with PdCl2 allowed to synthesize either [PdCl2(PyDTM)], in which the ligand is chelated by both sulfur atoms, or [PdCl2(PyDTM)2], in which the ligand acts as monodentat...
متن کاملTemplate Synthesis of Symmetrical Transition Metal Dithiocarbamates
Novos ditiocarbamatos de metais de transição do tipo [M 2 (etdtc) 2 ] e [M(etdtc)Cl] 2 [M = Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) e Hg(II), M = Cr(III), Fe(III) e etdtc = (S 4 N 4 C 11 H 18 )] foram sintetizados por meio de técnicas de automontagem. Os ditiocarbamatos metálicos foram preparados a partir da amina primária, CS 2 e cloreto metálico. Foram caracterizados por técnic...
متن کاملGlycosyl Dithiocarbamates: β-Selective Couplings without Auxiliary Groups
In this article, we evaluate glycosyl dithiocarbamates (DTCs) with unprotected C2 hydroxyls as donors in β-linked oligosaccharide synthesis. We report a mild, one-pot conversion of glycals into β-glycosyl DTCs via DMDO oxidation with subsequent ring opening by DTC salts, which can be generated in situ from secondary amines and CS2. Glycosyl DTCs are readily activated with Cu(I) or Cu(II) trifla...
متن کاملBifunctional dithiocarbamates: a bridge between coordination chemistry and nanoscale materials.
A dithiocarbamate-based methodology is employed to prepare linked heteromultimetallic complexes and then further exploited in the surface functionalisation of gold nanoparticles.
