| titleOfInvention | PROCESS FOR PRODUCING (ETHYNE-l,2-DIYL)BIS(ISOBENZOFURAN-l,3-DIONE) |
| abstract | Disclosed is a process for preparing (ethyn-l, 2-diyl) bis (isobenzofuran-1,3-dione). In the disclosed method, a homogeneous palladium catalyst, optionally copper salt, base, and optionally solvent in the presence of chloro-, bromo-, or iodoisobenzofuran-1,3-dione, optionally a copper salt, a base, and optionally another solvent Reacts with ethyne within. The (ethyn-1,2-diyl) bis (isobenzofuran-1,3-dione) prepared can then be washed with a cleaning agent, such as a carboxylic acid, a polar aprotic solvent, or chloroform. |
