The hexynes are a subgroup from the group of alkynes.It consists of several isomeric compounds having the formula C 6 H 10.. The linear and branched members are: 1-Hexyne (n-butylacetylene)
2-Hexyne can be semihydrogenated to yield 2-hexene or fully hydrogenated to hexane. [3] With appropriate noble metal catalysts it can selectively form cis-2-hexene. [4] 2-Hexyne can act as a ligand on gold atoms. [5] With strong sulfuric acid, the ketone 2-hexanone is produced. However this reaction also causes polymerization and charring. [6]
Methohexital can be synthesized in the classic manner of making barbituric acid derivatives, in particular by the reaction of malonic ester derivatives with derivatives of urea. [5] The resulting allyl-(1-methyl-2-pentynyl) malonic ester is synthesized by subsequent alkylation of the malonic ester itself, beginning with 2-bromo-3-hexyne, which ...
1-Hexyne can be prepared by the reaction of monosodium acetylide with butyl bromide: [1] NaC 2 H + BrC 4 H 9 → HC 2 C 4 H 9 + NaBr. Its reactivity illustrates the behavior of terminal alkylacetylenes. The hexyl derivative is common test substrate because it is conveniently volatile. It undergoes deprotonation at C-3 and C-1 with butyl lithium:
Chemical structure of 2-bromophenol. A bromophenol is an organic compound consisting of hydroxyl groups and bromine atoms bonded to a benzene ring. They may be viewed as hydroxyl derivatives of bromobenzene, or as brominated derivatives of phenol.
tert-Butyl bromide (also referred to as 2-bromo-2-methylpropane) is an organic compound with the formula Me 3 CBr (Me = methyl). The molecule features a tert-butyl group attached to a bromide substituent. This organobromine compound is used as a standard reagent in synthetic organic chemistry. It is a colorless liquid.

Structure of the coordination complex NbCl 3 (dimethoxyethane)(3-hexyne). [5] Together with a high-permittivity solvent (e.g. propylene carbonate), dimethoxyethane is used as the low-viscosity component of the solvent for electrolytes of lithium batteries. In the laboratory, DME is used as a coordinating solvent.
