Metal-free oxidative decarbonylative coupling of aromatic aldehydes with arenes: direct access to biaryls.
A metal-free oxidative decarbonylative coupling of aromatic aldehydes with electron-rich or electron-deficient arenes to produce biaryl compounds was developed. This novel coupling was proposed to proceed via a non-chain radical homolytic aromatic substitution (HAS) type mechanism, based on the substrate scope, ortho-regioselectivity, radical trapping experiments and DFT calculation studies. Wi...
متن کاملFacile access to 3,5-symmetrically disubstituted 1,2,4-thiadiazoles through phosphovanadomolybdic acid catalyzed aerobic oxidative dimerization of primary thioamides.
In the presence of Keggin-type phosphovanadomolybdic acids, e.g., H6PV3Mo9O40, oxidative dimerization of various kinds of primary thioamides including aromatic, heterocyclic, and aliphatic ones efficiently proceeded to give the corresponding 3,5-disubstituted 1,2,4-thiadiazoles in excellent yields.
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...
متن کاملMetal-free oxidative cyclization of acetophenones with diamines: a facile access to phenylpyridines.
An efficient metal-free access to 2- and 3-phenylpyridines via oxidative coupling of acetophenones or phenylacetones with 1,3-diaminopropane has been described. The reaction involves shorter reaction time, excellent yields and a broad substrate scope. The reaction proceeds via the formation of imine, which further undergoes oxidative C-N bond cleavage, C-C bond formation and oxidation to give a...
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...
