| titleOfInvention | Process for the production of 2-aryl-1,2,3-triazoles |
| abstract | 1,215,507. 2 - Aryl - 1,2,3 - triazole derivatives. FARBENFABRIKEN BAYER A.G. 20 Aug., 1968 [23 Aug., 1967], No. 39821/68. Heading C2C. The invention comprises a process of preparing 2 - aryl - 1,2,3 - triazoles of the Formula VI where R is an optionally substituted aryl or arylene radical (which term covers tolane and stilbene radicals as well as diarylene-alkane radicals) or a 3-phthalimide radical, R 1 is an optionally substituted aryl or alkyl radical, or a nitro group, R 2 is H or an optionally substituted alkyl or aryl radical and n is 1 or 2 by cyclizing an α-oximino-aryl hydrazone of the Formula VIII or an O-acyl derivative thereof by heating in urea at a temperature of 100 to 210 C. Examples include compounds of the Formula VI where R is a carboxylic acid substituted aryl radical; a sulphonic acid substituted aryl radical where R 1 may be aryl substituted by an alkoxy group; an acylamino substituted aryl or alkaryl radical; an aryl or alkaryl radical where R 1 is NO 2 ; or a nitro substituted aryl radical. The preparation of certain compounds of the Formula VIII is described; α-oximinopropiophenone - (3 - sulphophenyl) - hydrazine from phenylhydrazine - 3 - sulphonic acid and α- oximinopropiophenone; the disodium salt of 4,41 - bis - (α - oximinoacetophenone - hydrazono)- 1,2 - diphenyl - ethane - 2,2<SP>1</SP>- disulphonic acid from 4,4<SP>1</SP>-dihydrazino - 1,2 - diphenyl - ethane- 2,2<SP>1</SP> - disulphonic acid, oximinoacetophenone and saturated sodium chloride solution; oximinoacetophenone - hydrazono - 4 - benzoic acid from 4 - hydrazino - benzoic acid hydrochloride and oximinoacetophenone; and oximinoacetophenone - hydrazono - 4 - phenylacetic acid from 4-hydrazinophenyl-acetic acid and oximinoacetophenone. |
