In organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbon—carbon triple bond. 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.Alkynes are traditionally known as acetylenes, although the name acetylene also refers specifically to C 2 H 2, known ...
2-METHYL-2-HYDROXY-3-BUTYNE is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones.
The reaction dynamics of the dicarbon radical C 2 (a 3 Π u /X 1 Σ g +) in the singlet and triplet state with C 4 H 6 isomers 2-butyne, 1-butyne and 1,2-butadiene were investigated at collision energies of about 26 kJ mol −1 using the crossed molecular beam technique and supported by ab initio and RRKM calculations. The reactions are all indirect, forming C 6 H 6 complexes through ...
