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. | [General Description]
Maleimide (2,5-Pyrroledione) is a new nanoparticle surface functional group which favors easy conjugation with cell penetration peptides. The conjugation is enabled via click chemistry to preserve its biofunctions. | [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.] |
