meta-Aminophenols are formed by the action of DBU on 3-amino-2-chlorocyclohex-2-en-1-ones at room temperature in MeCN. The chloro compounds are generated by treating 3-aminocyclohex-2-en-1-ones with the easily prepared halogenating agent BnNMe3·ICl2 in Me

Inter-alkane amidogen phenolic synthetic method, its characteristic is: 1st step, between the two alkane amidogen acyl aniline and sulfuric acid aqueous solution mixing and heating to 50 - 110 °C, thermal insulation reaction of aniline [...] sulfuric acid aqueous solution; 2nd step, continue to drip the sodium nitrite aqueous solution, sodium nitrite aqueous solution for dropping temperature of - 10 - 20 °C, drop bi yu 5 - 30 °C insulation, [...] aniline obtained diazonium salt of the sulfuric acid aqueous solution; 3rd step, [...] aniline diazonium salt of the sulfuric acid aqueous solution is directly heated to 45 - 110 °C, thermal insulation, in the hydrolysis reaction of the diazonium salt, cooling after treatment, to obtain the product between two alkane amidogen phenol; three-step required by the reaction of sulfuric acid in the 1st step reaction in the finished disposable adding; a three-step reaction in a finish step by step in the pot. The method of the invention with raw materials are cheap, abundant, synthetic high security of the process, the product yield is high, the three waste less pollution and the like, has high industrial value.
