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 ]
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.
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.
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.
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
In neutralization reactions, basic oxides reacts with an acid to form salt and water: Magnesium oxide reacts with hydrogen chloride (acid) to produce magnesium chloride (salt) and water: MgO + 2 HCl → MgCl 2 + H 2 O; Sodium oxide reacts with hydrogen chloride (acid) to produce sodium chloride (salt) and water: Na 2 O + 2 HCl → 2 NaCl + H 2 O

A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.
