Maleimide Chemical Properties,Usage,Production

  • Chemical Properties slight yellow crystalline powder
  • Uses Rhodium-catalyzed conjugate arylation with arylboronic acids.1
  • Definition ChEBI: A cyclic dicarboximide in which the two carboacyl groups on nitrogen together with the nitogen itself form a 1H-pyrrole-2,5-dione structure.
  • Hazard A poison.
  • Safety Profile Poison by intraperitoneal and intravenous routes. An experimental teratogen. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of NOx.
  • Purification Methods Purify it by sublimation in a vacuum. The UV has max at 216 and 280nm in EtOH. [de Wolf & van de Straete Bull Soc Chim Belg 44 288 1935, UV: Rondestvedt et al. J Am Chem Soc 78 6115 1956, IR: Chiorboli & Mirone Ann Chim (Rome) 42 681 1952, Beilstein 21/10 V 3.]
