| titleOfInvention | Production of n-brominated organic compounds |
| abstract | N-Brominated organic compounds are prepared by treating an organic compound selected from imides of succinic, glutaric and phthalic acid and of alkyl and aryl succinic and glutaric acids; compounds RCONH2, where R is hydrogen, alkyl, cycloalkylalkyl, carboxyethyl, phenyl, alkylphenyl or phenylalkyl; hydantoins and 5,5-dialkyl, aryl and cycloaliphatic hydantoins; urea, biuret, oxamide, terephthalamide; and compounds H2NCO(CH2)nCONH2, where n is 2, 3 or 4; with bromine in an aqueous solution containing bromate ion at an acid pH. Chloride ion is also preferably present. The invention also comprises the compounds N,N1-dibromourea and 1,5-dibromo biuret. Examples prepare (1)-(5) N-bromosuccinimide, (6) N-bromoglutarimide, (7) N-bromophthalimide, (8) N-bromo-b -methylglutarimide, (9) N-bromo-a -phenylsuccinimide, (10) N-bromo-a -methylsuccinimide, (11) N-bromoformamide, (12), (13) N-bromoacetamide, (14) N-bromopropionamide, (15) N-bromobutyramide, (16) N-bromovaleramide, (17) N-bromobenzamide, (18) N-bromo-o-toluamide, (19) N-bromophenylacetamide, (20) N-bromocyclopentylpropionamide, (21) N,N1-dibromooxamide, (22) N,N1-dibromosuccindiamide, (23) N,N1-dibromoadipamide, (24) N,N1-dibrometerephthalamide, (25) succinic acid N-bromo-monoamide, (26) N,N1-dibromourea, (27) dibromobiuret, (28) 1,3-dibromohydantoin, (29) 1,3-dibromo-5,5-dimethylhydantoin, (30) 1,3-dibromo- 5-methyl-5-ethylhydantoin, (31) 1,3-dibromo- 5-methyl-5-isobutylhydantoin, (32) 1,3-dibromo-5,5-diphenylhydantoin, (33) 1,3-dibromo- 5,5-pentamethylenehydantoin, and (34) monobromo-5,5-dimethylhydantoin. Cyclohexene with N-bromosuccinimide or dibromobiuret in CCl4 gives 3-bromocyclohexene; with N-bromoacetamide it gives cyclohexenedibromide. Styrene with N-bromoacetamide or dibromobiuret in CCl4 gives styrene dibromide. |
