1-Ethynylcyclohexanol (ECX) is an alkynyl alcohol derivative which is both a synthetic precursor to, and an active metabolite of the tranquilizer ethinamate, and has similar sedative, anticonvulsant and muscle relaxant effects. It has been sold as a designer drug, first being identified in the UK in March 2012. [1] [2] [3] [4]
Ethinamate (1-ethynylcyclohexanone carbamate) is synthesized by combining acetylene with cyclohexanone to make 1-ethynylcyclohexanol, and then transforming this into a carbamate by the subsequent reaction with phosgene, and later with ammonia. Some lithium metal or similar is used to make the acetylene react with the cyclohexanone in the first ...

In organic chemistry, an ethynyl group is a functional group with the formula −C≡CH, representing an acetylene molecule with one fewer hydrogen atom.. Ethynyl group (HC≡C–), also designated as an acetylenic group (from acetylene), is referred to in IUPAC chemical nomenclature with the -yne suffix.
A copper chromite catalyst is usually used industrially. [1] The cis/trans ratio of the CHDM is affected by the catalyst. [2] Byproduct of this process are 4-methylcyclohexanemethanol (CH 3 C 6 H 10 CH 2 OH) and the monoester methyl 4-methyl-4-cyclohexanecarboxylate (CH 3 C 6 H 10 CO 2 CH 3, CAS registry number 51181-40-9).

In the example, there is a bromo-substituted -CH 2-CH 2 - subunit. 1-Bromoethane-1,2-diyl is chosen in preference to 2- bromoethane-1,2-diyl as the former has a lower locant for the bromo-substituent. The preferred CRU is therefore oxy(1-bromoethane-1,2-diyl) and the polymer is thus named poly[oxy(1-bromoethane-1,2-diyl)].
