In the original paper describing this reaction, methylmagnesium bromide is reacted with isophorone with and without 1 mole percent of added copper(I) chloride (see figure). [ 10 ] Without added salt the main products are alcohol B (42%) from nucleophilic addition to the carbonyl group and diene C (48%) as its dehydration reaction product.

Pigments that absorb in the yellow and red part of the visible spectrum can be added. As the dye absorbs light, the brightness of the paper will decrease, unlike the effect of an optical ...
Lithium diphenylcuprate etherate dimer from crystal structure Skeletal formula of lithium diphenylcuprate etherate dimer. Organocopper chemistry is the study of the physical properties, reactions, and synthesis of organocopper compounds, which are organometallic compounds containing a carbon to copper chemical bond.
Hauser bases, also called magnesium amide bases, are magnesium compounds used in organic chemistry as bases for metalation reactions. These compounds were first described by Charles R. Hauser in 1947. [ 1 ]
A sample of copper(I) oxide. Copper forms a rich variety of compounds, usually with oxidation states +1 and +2, which are often called cuprous and cupric , respectively. [ 1 ] Copper compounds , whether organic complexes or organometallics , promote or catalyse numerous chemical and biological processes.
Magnesium hydride was first prepared in 1951 by the reaction between hydrogen and magnesium under high temperature, pressure and magnesium iodide as a catalyst. [1] It reacts with water to release hydrogen gas; it decomposes at 287 °C, 1 bar: [2] MgH 2 → Mg + H 2. Magnesium can form compounds with the chemical formula MgX 2 (X=F

Like most amino acid complexes, the glycinate forms a 5-membered chelate ring, with the glycinato ligand serving as a bidentate (κ 2 Ο,Ν) species. [2] [5] The chelating ligands assume a square planar configuration around the copper atom as is common for tetracoordinate d 9 complexes, calculated to be much lower in energy than the alternative tetrahedral arrangement.
