| Abstract: | This paper reports that six new brominated and unbrominated phenol esters of 2, 4, 6-tribromobenzoic acid (2', 3', 5', 6'-tetrabromophenylene bis-2, 4, 6-tribromobenzoate; 2', 3', 4, 5', 6'-pentabromophenyl 2, 4, 6-tribromobenzoate;2', 4', 6'-tribromophenyl 2, 4, 6-tribromobenzoate: 4'-bromophenyl 2, 4, 6-tribromobenzoate: 4'-cresyl 2, 4, 6-tribromobenzoate and phenyl 2, 4, 6-tribromobenzoate) have been synthesized from m-amoinobenzoic acid available commercially. The proceedure used for the synthesis of the esters involves five steps:bromination, diazotisation, replacement of diazonium group by hydrogen, preparing acyl chloride and estification. The exact structures of the esters have been identified by means of quantative analysis of C, H and Br, and by spectroscopic examination of infrared and proton nuclear magnetic resonance. |
