ChemInform Abstract: Selective C-H Activation of Methoxy Groups in a Three-Component Photoreaction.

2016

Surprisingly, the photocatalytic activation of ethers by H-abstraction and addition of the generated radicals to iminium ions formed in situ from aldehydes and anilines predominantly yielded the products of methoxy activation for dimethoxymethane and 1,2-dimethoxyethane. Various anilines and aromatic as well as aliphatic aldehydes are suitable reaction partners for this three-component photoreaction (Porta-type process) which also provides a simple access to 1,2-aminoalcohols.

Crystal structure of catena-poly[[[(2-ethoxypyrazine-κN)copper(I)]-di-μ2-cyanido] [copper(I)-μ2-cyanido]]

2019

The title compound, {[Cu(EtOpz)(CN)2][CuCN]}n, where EtOpz is 2-eth­oxy­pyrazine, is a two-dimensional polymeric copper complex with different coordination environments of the two CuI ions. One Cu atom is coordinated to the 2-eth­oxy­pyrazine mol­ecule and two bridging cyanide ligands, equally disordered over two sites. The second Cu atom is coordinated by two disordered over two sites bridging cyanide groups. Two copper–cyanide chains are connected through Cu⋯Cu contact.

Tetrakis(dimethoxyboryl)methane

2016

The title compound, tetrakis(dimethoxyboryl)methane (systematic name: octamethyl methanetetrayltetraboronate), C9H24B4O8or C[B(OMe)2]4, is a useful synthetic intermediate. Crystals of this compound at 102 K conform to the orthorhombic space groupPbcn. The molecules, which reside on sites of crystallographic twofold symmetry, have idealized -4 point symmetry like most other CX4molecules in which eachXgroup bears two non-H substituents at the 1-position. The central C atom has a slightly distorted tetrahedral coordination geometry, with C—B bond lengths of 1.5876 (16) and 1.5905 (16) Å. One of the methoxy groups is disordered over two sets of sites; the major component has an occupancy factor…

Effect of Antioxidants on Microsomal Enzymes of Rat Liver

1978

Rat diet was supplemented with butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA) or ethoxyquin (EQ) for 14 days, and hepatic microsomal epoxide hydratase (EH) and monooxygenase were subsequently studied in vitro. The antioxidants increased EH activity. The increase was marked with BHT (factor 3) and EQ (factor 4) and was paralleled by an increase in a protein band on SDS polyacrylamide gels which migrated together with purified rat hepatic EH. A slight but nonsignificant increase in cytochrome P450 content and a moderate increase in ethoxycoumarin deethylation and cytochrome b5 content was also observed while aryl hydrocarbon hydroxylase (AHH) activity was not elevated. Irrever…
