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 ...
Isoamyl alcohol is a colorless liquid with the formula C 5 H 12 O, specifically (H 3 C–) 2 CH–CH 2 –CH 2 –OH. It is one of several isomers of amyl alcohol (pentanol). It is also known as isopentyl alcohol, isopentanol, or (in the IUPAC recommended nomenclature) 3-methyl-butan-1-ol.
For example, the three isomers of xylene CH 3 C 6 H 4 CH 3, commonly the ortho-, meta-, and para-forms, are 1,2-dimethylbenzene, 1,3-dimethylbenzene, and 1,4-dimethylbenzene. The cyclic structures can also be treated as functional groups themselves, in which case they take the prefix "cyclo alkyl -" (e.g. "cyclohexyl-") or for benzene, "phenyl-".
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 ...
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 ...
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.
Butenoic acid is any of three monocarboxylic acids with an unbranched 4-carbon chain with 3 single bonds and one double bond; that is, with the structural formula HO(O=)C – CH=CH – CH 2 –H (2-butenoic) or HO(O=)C – CH 2 – CH=CH –H (3-butenoic). All have the chemical formula C 3 H 5 COOH or C 4 H 6 O 2.
