3-Hexyne is the organic compound with the formula C 2 H 5 CCC 2 H 5. This colorless liquid is one of three isomeric hexynes. 3-Hexyne forms with 5-decyne, 4-octyne, and 2-butyne a series of symmetric alkynes. It is a reagent in organometallic chemistry. [1] Structure of the coordination complex NbCl 3 (dimethoxyethane)(3-hexyne). [2]
It consists of several isomeric compounds having the formula C 6 H 10. ... 2-Hexyne (methylpropylacetylene) 3-Hexyne (diethylacetylene) 3-methylpent-1-yne; 4 ...
1-Hexyne is a hydrocarbon consisting of a straight six-carbon chain having a terminal alkyne. Its molecular formula is HC 2 C 4 H 9 . A colorless liquid, it is one of three isomers of hexyne. [ 1 ]
In organic chemistry, hexene is a hydrocarbon with the chemical formula C 6 H 12.The prefix "hex" is derived from the fact that there are 6 carbon atoms in the molecule, while the "-ene" suffix denotes that there is an alkene present—two carbon atoms are connected via a double bond.
Structure of NbCl 3 (dimethoxyethane)(3-hexyne). [2]Nb 3 Cl 8 is produced by reduction of niobium(V) chloride with hydrogen, or just by heating.. Salt-free reduction of dimethoxyethane solution of NbCl 5 with 1,4-disilyl-cyclohexadiene in the presence of 3-hexyne produces the coordination complex NbCl 3 (dimethoxyethane)(3-hexyne):
5-Decyne, also known as dibutylethyne, is a type of alkyne with a triple bond at its fifth carbon (the '5-' indicates the location of the triple bond in the chain). Its formula is C 10 H 18 . Its density at 25 °C and otherwise standard conditions is 0.766 g/ml. [ 1 ] The boiling point is 177 °C. [ 2 ]
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.
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]
