Oxidizing Morita–Baylis–Hillman adducts towards vicinal tricarbonyl compounds

Photochemistry of Cyclic Vicinal Tricarbonyl Compounds. Photochemical Reaction of 1,2,3- Indanetrione with 2,3-Dimethyl-2-butene: Hydrogen Abstraction and Photocycloaddition

A irradiação na região do ultravioleta de 1,2,3-indanotriona, em presença de 2,3-dimetil-2buteno, em diclorometano, leva a uma mistura complexa de produtos formados a partir de reações de abstração de hidrogênio, fotocicloadição [2π+2π] (reação de Paternò-Büchi) e fotocicloadição [4π+2π]. A distribuição de produtos é dependente de fatores eletrônicos e estéricos, com estes últimos sendo os resp...

Missing Iron-Oxidizing Acidophiles Highly Sensitive to Organic Compounds

The genus Acidithiobacillus includes iron-oxidizing lithoautotrophs that thrive in acidic mine environments. Acidithiobacillus ferrooxidans is a representative species and has been extensively studied for its application to the bioleaching of precious metals. In our attempts to cultivate the type strain of A. ferrooxidans (ATCC 23270(T)), repeated transfers to fresh inorganic media resulted in ...

Benzene-1,3,5-tricarbonyl trichloride

In the title molecule, C(9)H(3)Cl(3)O(3), there are three short interactions involving the benzene H atoms and the chloro-formyl Cl atoms. In the crystal, mol-ecules stack along the a axis with no significant non-bonded inter-actions.

Organosulfur compounds from garlic (Allium sativum) oxidizing canine erythrocytes.

The sulfurous acid ester, trans-sulfurous acid allyl ester 3-allylsulfanyl-allyl ester 8, along with two known thiosulfinates was isolated from the aqueous ethanol extract of garlic (Allium sativum). The chemical structure of 8 was determined on the basis of spectroscopic data including high resolution mass and two-dimensional NMR techniques. All of these compounds induced methemoglobin formati...
