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]
As early as 1938, G. N. Lewis pointed out that the relative strength of an acid or base depended upon the base or acid against which it was measured. [1] No single rank order of acid or base strength can predict the energetics of the cross reaction. Consider the following pair of acid–base reactions:. 4F-C 6 H 4 OH + OEt 2 −ΔH = 5.94 kcal/mole

Another example is the bicyclic OBO protecting group (4-methyl-2,6,7-trioxa-bicyclo[2.2.2]octan-1-yl) which is formed by the action of (3-methyloxetan-3-yl)methanol on activated carboxylic acids in the presence of Lewis acids. The group is base stable and can be cleaved in two steps under mild conditions, mildly acidic hydrolysis yields the ...
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 ...
Hantzsch ester refers to an organic compound with the formula HN(MeC=C(CO 2 Et)) 2 CH 2 where Me = methyl (CH 3) and Et = ethyl (C 2 H 5).It is a light yellow solid. The compound is an example of a 1,4-dihydropyridine.
1-Hexanol (IUPAC name hexan-1-ol) is an organic alcohol with a six-carbon chain and a condensed structural formula of CH 3 (CH 2) 5 OH. This colorless liquid is slightly soluble in water, but miscible with diethyl ether and ethanol .
Isethionic acid is an organosulfur compound containing an alkyl sulfonic acid located beta to a hydroxy group. Its discovery is generally attributed to Heinrich Gustav Magnus , who prepared it by the action of solid sulfur trioxide on ethanol in 1833. [ 1 ]
