Dimedone
Dimedone is a cyclic diketone used in organic chemistry to determine whether a compound contains an aldehyde group. Cyclohexanediones in general can be used as catalysts in the formation of transition-metal complexes. Other uses include applications in colorimetry, crystallography, luminescence and spectrophotometric analysis. It can also be used for chemistry involving organic compounds of low electrical resistance.
Synthesis
Dimedone is prepared from mesityl oxide and diethyl malonate.
Physical properties
Dimedone usually comes in the form of white crystals. It is stable under ambient conditions and soluble in water, as well as ethanol and methanol. It has a melting point range of 147–150 °C (420–423 K).
Tautomerism
Dimedone is in equilibrium with its tautomer in solution — in a 2:1 keto to enol ratio in chloroform.
Crystalline dimedone contains chains of molecules, in the enol form, linked by hydrogen bonds:

Turn It On Salvador
by: Toy MatineeTurn it on, Salvador
Drag the bound priest across the floor
Skin to shed, God is dead, what to do, so are you
Are you?
Wake them up, shake 'em up
Death and a gala premiere
Turn it on, Salvador
Brutally offensive, but never a bore
Ants in hands, no demands, eyeing out a point of view
Or two
Bang them out, hang them up
Nothing is what it appears
Didn't he say how he likes to make the holes?
Time melts away while he tries to make the holes
Turn it on, Salvador
Turn it off, Salvador
Holy rotting donkey carcass butterfly eeeeee
Even tied, eggs you fried, out of luck
What the (some 15th century German word)
(Some 15th century German word)
Books are guns, biking nuns
Ants, sirs, they crawl from the wounds
Didn't he say how he likes to make the holes?
Time melts away while he tries to make the holes
Turn it on, Salvador
Da da da da da da
