Pyrrolidine 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 کاملHeavy 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...

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 کاملConstruction of tetrahydrofurans by PdII/PdIV-catalyzed aminooxygenation of alkenes.
Catalytic transformations involving Pd s-alkyl or s-aryl intermediates are widely used in organic synthesis and offer attractive routes to many valuable products. However, the vast majority of these reactions proceed by Pd/Pd mechanisms. As a result, the diversity of structures/bonds that can be constructed is constrained by the limitations of this redox cycle. Recent studies have explored the ...
متن کاملThe Evolution of Pd0/PdII-Catalyzed Aromatic Fluorination
Aromatic fluorides are prevalent in both agrochemical and pharmaceutical agents. However, methods for their rapid and general preparation from widely available starting materials are limited. Traditional approaches such as the Balz-Schiemann and Halex reactions require harsh conditions that limit functional group tolerance and substrate scope. The use of transition metals to affect C-F bond for...
