2-Butyne is of interest to physical chemists because of its very low torsional barrier and the problem of determining that barrier using high-resolution infrared spectroscopy. Analysis of its spectrum [3] leads to a determination that the torsional barrier is only 6 cm −1 (1.2 × 10 −22 J or 72 J mol −1).
The addition can be promoted with base [1] (Favorskii reaction) or with Lewis acid catalysts. [2] 2-Methylbut-3-yn-2-ol is produced on an industrial scale as a precursor to terpenes and terpenoids. 2-Methylbut-3-yn-2-ol is an intermediate in this industrial route to geraniol. [3] 2-Methylbut-3-yn-2-ol also is used as a monoprotected version of ...
Isoprenol, also known as 3-methylbut-3-en-1-ol, is a hemiterpene alcohol. It is produced industrially as an intermediate to 3-methylbut-2-en-1-ol (prenol): global production in 2001 can be estimated as 6–13 thousand tons.
A 3D model of ethyne (), the simplest alkyneIn organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbon—carbon triple bond. [1] The simplest acyclic alkynes with only one triple bond and no other functional groups form a homologous series with the general chemical formula C n H 2n−2.
1-Butyne is an organic compound with the formula CH 3 CH 2 C≡CH. It is a terminal alkyne. The compound is a common terminal alkyne substrate in diverse studies of catalysis. It is a colorless combustible gas. [1] 1-Butyne participates in reactions typical for terminal alkynes, such as alkyne metathesis, [2] hydrogenation, condensation with ...
1-Butene (IUPAC name: But-1-ene, also known as 1-butylene) is the organic compound with the formula CH 3 CH 2 CH=CH 2. It is a colorless gas. But-1-ene is an alkene easily condensed to give a colorless liquid. It is classified as a linear alpha-olefin (terminal alkene). [2] It is one of the isomers of butene (butylene). It is a precursor to ...
[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.
