Rotbergs, J.; Oskaja, V. published the artcile< Condensation of 3-bromophthalic anhydride with β-dicarbonyl compounds>, Safety of 4-Bromoisobenzofuran-1,3-dione, the main research area is phthalic anhydride condensation; bromo indandionecarboxylic acid; dicarbonyl compound condensation.
3-Bromophthalic anhydride (I) condensed with AcCH2CO2Et in Ac2O-Et3N gave 85.9% II. Ir spectra of condensation products of I with AcCH2Ac, BzCH2Ac, BzCH2Bz, and CH2(CO2Et)2 were compared.
Uch. Zap. Latv. Univ. published new progress about 82-73-5. 82-73-5 belongs to class bromides-buliding-blocks, and the molecular formula is C8H3BrO3, Safety of 4-Bromoisobenzofuran-1,3-dione.
