Resorcine (Benzodiazepines) can occur double enol tautomerism - diketone, can react by double enol form (e.g., acetoxylation), can also according to the double ketone reaction (generated dual oxime).It is more easy than phenol electrophilic aromatic substitution reaction and Houben - Hoesch reaction.
Resorcinol with lead acetate generated precipitation (catechol and lead acetate generates precipitation), but can and Lin reagent and silver ammonia solution of ophir.With ferric chloride solution into a purple.With bromine water, precipitation between the three bromine benzodiazepines.Be sodium amalgam restoration, generate between dihydrogen benzodiazepines (1, 3 - ring adipic ketone).The latter with strong barium hydroxide solution when heated to 150-150 ° C, generating gamma - acetyl butyric acid.Under the effect of sulfuric acid and zinc chloride, the resorcinol reaction with phthalic anhydride, generate fluorescent yellow fluorescent dye.
Resorcinol reaction in the presence of sulfuric acid and nitric acid in cold, generate yellow crystalline convergence acid (2 minus 2-3 nitro resorcinol).Convergence acid explosion during rapid heating, the lead salt lead acid (convergence) lead acid, also known as Stephen used as explosives.
