Reaction

The Reaction With Dmg Gives Ni(dmg)2 2+(aq)

Dimethylglyoxime is a chemical compound described by the formula CH3C(NOH)C(NOH)CH3. Its abbreviation is dmgH2 for neutral form, and dmgH for anionic form, where H stands for hydrogen. This colourless solid is the dioxime derivative of the diketone butane-2,3-dione (also known as diacetyl). DmgH2 is used in the analysis of palladium or nickel. Its coordination complexes are of theoretical interest as models for enzymes and as catalysts. Many related ligands can be prepared from other diketones, e.g. benzil.

Preparation[edit]

Dimethylglyoxime can be prepared from butanone first by reaction with ethyl nitrite to give biacetyl monoxime. The second oxime is installed using sodium hydroxylamine monosulfonate:[1]

Complexes[edit]

Balance the reaction of Ni + (Dmg) = Ni(Dmg)2 using this chemical equation balancer! Dimethylglyoxime DMG, (CH 3 CNOH) 2 is used as a reagent to precipitate nickel ion. Assume that 53.0 g of DMC has been dissolved in 525 g of ethanol (C 2 H 5 OH). S The red, insoluble compound formed between nickel(II)ion and dimethylglyoxime (DMG) is precipitated when DMG is added to a bask solution of Ni 2+ (aq). Chemical Equation Balancer C2H2Cl2 + H2O = C2H2(OH)2 + HCl. Balanced Chemical Equation. C 2 H 2 Cl 2 + 2 H 2 O = C 2 H 2 (OH) 2 + 2 HCl. Reaction Information. Reaction Type.

Dimethylglyoxime is used to detect and quantify nickel, which forms the bright red complex nickel bis(dimethylglyoximate) (Ni(dmgH)2). The reaction was discovered by L. A. Chugaev in 1905.[2]

Cobalt complexes have also received much attention. In chloro(pyridine)cobaloxime[3] the macrocycle [dmgH]22− mimics the macrocyclic ligand found in vitamin B12.
