In the presence of [Cp*RhCl2]2 and AgSbF6, perylenediimides underwent chemoselective and regioselective iodination with N-iodosuccinimide mediated by Cu(OAc)2 in 1,2-dichloroethane to yield ortho-tetraiodination perylenediimides I [R = (BuCH2CH2)2CH, Et2CH] in 71-89% yields; the reactions were performed on multigram scale. Mono-, di-, and triiodinated perylenediimides were prepared chemoselectively by varying the reaction conditions and solvent. I [R = (BuCH2CH2)2CH] underwent Suzuki and Sonogashira coupling reactions and substitution with aniline, thiophenol, and phenol to give tetrasubstituted perylenediimides; Sonogashira coupling with dialkynes yielded conjugated microporous polymers. The UV/visible spectra, fluorescence behavior, reduction potentials, and calculated HOMO and LUMO energies of I [R = (BuCH2CH2)2CH] and its coupling products were determined The structure of I (R = Et2CH) was determined by X-ray crystallog. In the experiment, the researchers used many compounds, for example, 2,9-Di(tridecan-7-yl)anthra[2,1,9-def:6,5,10-d’e’f’]diisoquinoline-1,3,8,10(2H,9H)-tetraone (cas: 110590-84-6Recommanded Product: 110590-84-6).
2,9-Di(tridecan-7-yl)anthra[2,1,9-def:6,5,10-d’e’f’]diisoquinoline-1,3,8,10(2H,9H)-tetraone (cas: 110590-84-6) belongs to isoquinoline derivatives. Although isoquinoline derivatives can be synthesized by several methods, relatively few direct methods deliver the unsubstituted isoquinoline. Isoquinoline-type alkaloids show biological activities similar to those of morphinane-, protoberberine-, and benzophenanthridine-type alkaloids.Recommanded Product: 110590-84-6
