Abstract:
The chemistry and the mechanism of the Bruylant’s test for 2,2’dimorphine have been cleared. Molybdic acid is obtained via metathesis from ammonium molybdate and sulphuric acid, The reactive species is protonated molybdic acid which in combination with the electrodotic property of a phenol in the bimorphine forms a mixed molybdate. Interaction of the remaining hydroxyl group in the molybdate moiety with a hydrion produces a synchronous mechanism involving five electron-shifts. Water and molybdenum dioxide are formed. An electron deficient oxygen originates two double bond shifts and an enedione is afforded as final product. This grouping is present also in indigo blue and besides MoO2 is violet.
