Nucleophilic reactivity of copper(ii)-alkylperoxo complexes.
Copper(ii)-alkylperoxo adducts, [Cu(CHDAP)(OOR)]+ (CHDAP = N,N'-dicyclohexyl-2,11-diaza[3,3](2,6)pyridinophane; R = C(CH3)2Ph and tBu), were prepared and characterized using various physicochemical methods. These are the first synthetic Cu(ii)-alkylperoxo complexes that can perform aldehyde deformylation (i.e., nucleophilic reactivity) under the stoichiometric reaction conditions, which was con...
متن کاملReactivity ratios for organotin copolymer systems.
Di(tri-n-butyltin) itaconate (DTBTI) and monoethyl tributyltin fumarate (METBTF) were synthesized as organotin monomers. The organotin monomers were copolymerized with styrene (ST) and methyl methacrylate (MMA) via a free radical polymerization technique. The overall conversion was kept low (<or=15% wt/wt) for all studied samples and the copolymer composition was determined from tin analysis. T...
متن کاملSynthesis and characterization of organotin containing copolymers: reactivity ratio studies.
Organotin monomers containing dibutyltin groups--dibutyltin citraconate (DBTC) as a new monomer and dibutyltin maleate (DBTM)--were synthesized. Free radical copolymerizations of the organotin monomers with styrene (ST) and butyl acrylate (BA) were performed. The overall conversion was kept low (< or = 15% wt/wt) for all studied samples and the copolymers composition was determined from tin ana...
متن کاملNucleophilic reactivity of a copper(II)-superoxide complex.
Metal-bound superoxide intermediates are often implicated as electrophilic oxidants in dioxygen-activating metalloenzymes. In the nonheme iron α-ketoglutarate dependent oxygenases and pterin-dependent hydroxylases, however, Fe(III)-superoxide intermediates are postulated to react by nucleophilic attack on electrophilic carbon atoms. By reacting a Cu(II)-superoxide complex (1) with acyl chloride...
متن کاملOrganotin Compounds and the Environment
Organotin compound that have at least one Sn-C bond have wide commercial applications as PVC stabilizer, antifouling agent in paint and as agrochemicals. The general formula for organotin compounds is R4SnX4 - n where R is normally alkyl or aryl groups and X=Cl-, OH-, CH3COO- . If n=3, the compound has the highest toxicity, for example Et3SnOAC has LD 50 4mg/Kg ( rats ) and this is the m...
