  • PROCESS FOR PRODUCING (ETHYNE-1,2-DIYL)BIS(ISOBENZOFURAN-1,3-DIONE)
    Publication number: 20150080586
    Abstract: A process for obtaining (ethyne-1,2-diyl)bis(isobenzofuran-1,3-dione) is disclosed. In the disclosed process chloro-, bromo-, or iodoisobenzofuran-1,3-dione is reacted with ethyne in a solvent in the presence of a dissolved homogenous palladium catalyst, optionally a copper salt, a base, and optionally a solvent distinct from said base. Subsequently the obtained (ethyne-1,2-diyl)bis(isobenzofuran-1,3-dione) may be washed with a washing agent, such as a carboxylic acid, a polar aprotic solvent, or chloroform.
