A V(III) thiolate complex activated C-Cl bond in dichloromethane via S-based nucleophilic attack. The reaction products, a V(III)-Cl species (major one) and a V(IV) binding to a CH(2) containing ligand (minor one) were obtained. The work demonstrates sulfur donors in the early-transition metal thiolates having strong nucleophilic characteristics.

The crystal structure of the title compound, [Co(3)(C(5)H(9)O(2))(6)O(CH(4)O)(3)]Cl, consists of trinuclear Co(III) complex cations and chloride anions. The Co(III) cation has site symmetry m, and is coordinated by four oxygen atoms from four bridging pivalate groups, one central O anion and a methanol oxygen atom, forming a distorted octa-hedral geometry. The coordinated methanol mol-ecule is ...

The present study aimed to compare the results of hand-assisted laparoscopic surgery (HALS) and conventional laparotomy (CL) at a single institution in Japan. Of the 212 patients with stage I/II/III colorectal cancer who received a curative resection, 98 patients underwent HALS and 114 patients underwent CL. The clinical background and post-operative management did not differ between the two gr...

The chemoselective photoreduction of aldehydes in the presence of ketones was achieved using triethanolamine (TEOA) as sacrificial electron donor, proflavine (PF) as photocatalyst and [Cp*Rh(iii)(bpy)Cl]Cl (Rhcat) as mediator. The reducing agent, which reacts with the carbonyl group was found to be [Cp*Rh(iii)(bpy)H]Cl (Rh(iii)-H). Contrary to formate-based reduction, its slow photochemical in ...

A modified pH 1.0 liquid redox sulfur recovery (LRSR) process, based on reactive absorption of H(2)S((g)) in an acidic (pH 1.0) iron solution ([Fe(III)] = 9-8 g L(-1), [Fe(II)] = 1-2 g L(-1)) and electrochemical regeneration of the Fe(III)/Fe(II) catalyst couple, is introduced. Fe(II) was oxidized in a flow-through electrolytic cell by Cl(2(aq)) formed on a Ti/RuO(2) anode. pH 1.0 was applied t...

Reactions of salicylaldehyde 4-methylthiosemicarbazone (H2L) and salicylaldehyde 4phenylthiosemicarbazone (H2L) with assorted chromium(III) precusors, [Cr(H2O)6]Cl3, [Cr(H2O)6](NO3)33H2O and [Cr(H2O)6](CH3COO)3, afforded new mononuclear chromium(III) complexes of the general formula [Cr(HL)2]X (X = Cl, NO3 and CH3COO). In all isolated compounds, Cr(III) ion is coordinated by the O,N,S atoms of...

In the title compound, (C(7)H(10)N)(3)[SbCl(5)]Cl, the Sb(III) cation is coordinated by five Cl(-) anions in a distorted square-pyramidal geometry, in which the longest Sb-Cl distance of 3.0319 (14) Å indicates a weak coordination bond. In the crystal, the 3-methyl-anilinium cations link with the complex antimonate anions and Cl(-) anions via N-H⋯Cl hydrogen bonds.

The title compound, hexa-mu-chloro-1:2kappa(4)Cl;2:3kappa(4)Cl;3:4kappa(4) Cl-hexachlor o-1kappa(2)Cl,2kappaCl,3kappaCl, 4kappa(2)Cl-hexakis(diethylamine)-1kappa(2)N,2kappa N,3kappaN, 4kappa(2)N-tetraindium(III), [(InCl(3))(4)(Et(2)NH)(6)] or [In(4)Cl(12)(C(4)H(11)N)(6)], lies about an inversion centre and consists of four octahedrally coordinated In centres linked by bridging Cl atoms to form ...

Um método simples e sensível baseado na análise de quimiluminescência por injeção em fluxo acoplado ao complexo luminol-Ag(III) foi desenvolvido para se determinar ácido úrico (UA) em urina humana. O método se baseia na reação de quimiluminescência (CL) do luminol com Ag(III) em solução alcalina, sendo que o UA da urina aumenta dramaticamente as intensidades CL. Em condições ótimas, a intensida...
