Most famously, at least in the classroom, pinacolone arises by the pinacol rearrangement, which occurs by protonation of pinacol (2,3-dimethylbutane-2,3-diol). [4] Industrially pinacolone is made by the hydrolysis of 4,4,5-trimethyl-1,3-dioxane, which is the product of isoprene and formaldehyde via the Prins reaction.
Pinacol is a branched alcohol which finds use in organic syntheses. It is a diol that has hydroxyl groups on vicinal carbon atoms. A white solid that melts just above room temperature, pinacol is notable for undergoing the pinacol rearrangement in the presence of acid and for being the namesake of the pinacol coupling reaction.
Neopentyl glycol (IUPAC name: 2,2-dimethylpropane-1,3-diol) is an organic chemical compound. It is used in the synthesis of polyesters , paints , lubricants , and plasticizers . When used in the manufacture of polyesters, it enhances the stability of the product towards heat, light, and water.
Skeletal formula of 2,3-dimethylbutane with some implicit hydrogens shown: Ball and stick model of 2,3-dimethylbutane: Names Preferred IUPAC name. 2,3-Dimethylbutane [1]
2,3-Dimethyl-1-butene is an organic compound with the formula CH 2 =C(CH 3)CH(CH 3) 2. Like the other isomers of dimethylbutene , it is a colorless liquid. Together with 2,3-dimethyl-2-butene it can be produced by dimerization of propylene .
Dimethylbutene is an alkene with a molecular formula C 6 H 12. It has the following possible structural isomers: 2,3-Dimethyl-1-butene; 3,3-Dimethyl-1-butene;
[2] [5] The compound is used as a reactant in the synthesis of a number of compounds. Notably it is used to synthesize 2,3-dimethylbut-2-ene, and is then converted to 2,3-dimethylbutane-2,3-diol and methyl tert-butyl ketone, better known as pinacolone. Pinacolone itself is then used in synthesis for number of pesticides.
DMB inhibits microbial trimethylamine (TMA) formation in mice and in human feces, thereby reducing plasma trimethylamine N-oxide (TMAO) levels after choline or carnitine supplementation. [1] It consequently inhibited choline-enhanced endogenous macrophage foam cell formation and atherosclerotic lesion development in mice without alterations in ...
