Chalcone derivative and its preparation |
| abstract |
NEW MATERIAL:A chalcone derivative expressed by formulaI(X is halogen; R is aryl or heterocyclic group). n EXAMPLE: 4-Nitro-4'-monochloroacetyloxychalcone. n USE: A raw material for photosensitive resins capable of giving the resin having a high sensitivity due to the absorption in the long wavelength region. n PROCESS: A 4'-hydroxychalcone expressed by formula II is reacted with a monohaloacetyl chloride expressed by the formula XCH 2 COCl in the prsence of a solid alkaline catalyst, e.g. potassium carbonate or sodium carbonate, at 20W 100°C to give the compound expressed by formulaI. n COPYRIGHT: (C)1982,JPO&Japio |
