Zinc nitrate is usually prepared by dissolving zinc metal, zinc oxide, or related materials in nitric acid: Zn + 2 HNO 3 → Zn(NO 3) 2 + H 2 ZnO + 2 HNO 3 → Zn(NO 3) 2 + H 2 O. These reactions are accompanied by the hydration of the zinc nitrate. The anhydrous salt arises by the reaction of anhydrous zinc chloride with nitrogen dioxide: [1]
Organozinc compounds contain zinc—carbon covalent bonds. Diethylzinc ((C 2 H 5) 2 Zn) was first reported in 1848. It was made by reaction of zinc and ethyl iodide and is the first compound known to contain a metal—carbon sigma bond. [25] For a long time it was a mystery why copper(II) did not form an analogous compound.
Zinc azide Zn(N 3) 2 is an inorganic compound composed of zinc cations (Zn 2+) and azide anions (N − 3). It is a white, explosive solid that can be prepared by the protonolysis of diethylzinc with hydrazoic acid: [1] Zn(C 2 H 5) 2 + 2 HN 3 → Zn(N 3) 2 + 2 C 2 H 6
Upon mixing of concentrated hydrochloric acid and concentrated nitric acid, chemical reactions occur. These reactions result in the volatile products nitrosyl chloride and chlorine gas: HNO 3 + 3 HCl → NOCl + Cl 2 + 2 H 2 O. as evidenced by the fuming nature and characteristic yellow color of aqua regia.
Organozinc compounds that are strongly Lewis acidic are vulnerable to nucleophilic attack by alkali metals, such as sodium, and thus form these 'ate compounds'. Two types of organozincates are recognized: tetraorganozincates ([R 4 Zn]M 2), which are dianionic, and triorganozincates ([R 3 Zn]M), which are monoanionic. Their structures, which are ...
The oxygen on an aldehyde or ketone coordinates to the zinc to form the six-member chair like transition state 3. A rearrangement occurs in which zinc switches to the aldehyde or ketone oxygen and a carbon-carbon bond is formed 4. Acid workup 5,6 removes zinc to yield zinc(II) salts and a β-hydroxy-ester 7. [5]
A multi-component reaction (or MCR), sometimes referred to as a "Multi-component Assembly Process" (or MCAP), is a chemical reaction where three or more compounds react to form a single product. [1] By definition, multicomponent reactions are those reactions whereby more than two reactants combine in a sequential manner to give highly selective ...
Zinc nitride reacts violently with water to form ammonia and zinc oxide. [3] [4] Zn 3 N 2 + 3 H 2 O → 3 ZnO + 2 NH 3. Zinc nitride reacts with lithium (produced in an electrochemical cell) by insertion. The initial reaction is the irreversible conversion into LiZn in a matrix of beta-Li 3 N. These products then can be converted reversibly and ...
