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. It is a precursor to the commercial fragrance tonalide. [1]

It can be prepared by base-catalyzed isomerization of 2,3-dimethyl-1-butene. [2] Another route involves direct dimerization of propylene. [3] It can also be produced by photolysis of tetramethylcyclobutane-1,3-dione. [4]
Dimethylbutadiene, formally referred to as 2,3-dimethyl-1,3-butadiene, is an organic compound with the formula (CH 3) 2 C 4 H 4. It is colorless liquid which served an important role in the early history of synthetic rubber .
2,3-Dimethylbutane is an isomer of hexane. It has the chemical formula (CH 3) 2 CHCH(CH 3) 2. It is a colorless liquid which boils at 57.9 °C. References
Pinacolone (3,3-dimethyl-2-butanone) is an important ketone in organic chemistry. It is a colorless liquid with a slight peppermint or camphor odor. It is a precursor to triazolylpinacolone in the synthesis of the fungicide triadimefon and in synthesis of the herbicide metribuzin. The molecule is an unsymmetrical ketone. The α-methyl group can ...
For example, the relative rates of epoxidation increase upon methyl substitution of the alkene (the methyl groups increase the electron density of the double bond by hyperconjugation): ethylene (1, no methyl groups), propene (24, one methyl group), cis-2-butene (500, two methyl groups), 2-methyl-2-butene (6500, three methyl groups), 2,3 ...
2,2-Dimethylbutane, trivially known as neohexane at William Odling's 1876 suggestion, [4] is an organic compound with formula C 6 H 14 or (H 3 C-) 3-C-CH 2-CH 3. It is therefore an alkane , indeed the most compact and branched of the hexane isomers — the only one with a quaternary carbon and a butane (C 4 ) backbone.
