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.

Percent Yield = x 100% Actual yield (g or mol) Theoretical yield (g or mol) If, in the thermite reaction described on the previous slides, we obtained only 60.3 g of Fe instead of the 69.9 g we expected based on total consumption of the Al, the percent yield would have been: 60.3 69.9 x 100 = 86.3%.
- The reaction is performed in a solution buffered by either an ammonia or citrate buffer to prevent the pH of the solution from falling below 5. If the pH does become too low the equilibrium of the above reaction favors the formation of the nickel (II) ion, causing the dissolution of Ni (DMG) 2 back into the mother liquor.
- PDF Nickel-dimethylglyoxime complex (abbreviated as Ni(II)(DMG)2) modified carbon paste and graphite electrodes were prepared by mixing Ni(II)(DMG)2 with graphite paste, and coating Ni(II)(DMG)2.
- Ni2+(aq) + 2DMG-Ni(DMG)2(s) The red Ni(DMG)2 is neutral and there are no ion-dipole interactions with H2O molecules so the cmplx is highly insoluble and hence the top equilibrium is tipped to the right until the rxn is complete. This rxn was used for decades for the gravimetric determination of Ni (I did it as an undergraduate!).

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]
