Zipping up Tetraazaperylene: Synthesis of Tetraazacoronenes via Double Coupling in the Bay Positions [data]
Feb 20, 2024
Eichelmann, Robert; Rippel, Daniel; Ballmann, Joachim; Gade, Lutz H., 2024, "Zipping up Tetraazaperylene: Synthesis of Tetraazacoronenes via Double Coupling in the Bay Positions [data]", https://doi.org/10.11588/data/HIERR9, heiDATA, V1
Substituted tetraazacoronene fluorophores have been obtained selectively by double Suzuki–Miyaura cross coupling of symmetrically substituted 1,2-bis(pinacolatoboryl)alkenes with a bay-substituted octaazaperopyrenedioxide (OAPPDO). Subsequent Scholl reaction of the dimethoxypheny...
Chiral Bay-Alkynylated Tetraazaperylenes: Photophysics and Chiroptical Properties
Feb 20, 2024
Eichelmann, Robert; Jeudy, Pierre; Schneider, Lars; Zerhoch, Jonathan; Mayer, Paula R.; Ballmann, Joachim; Deschler, Felix; Gade, Lutz H., 2024, "Chiral Bay-Alkynylated Tetraazaperylenes: Photophysics and Chiroptical Properties", https://doi.org/10.11588/data/PGSVXO, heiDATA, V1
Fully bay-alkynylated octaazaperopyrene dioxide (OAPPDO) derivatives were accessible through Stille cross coupling reaction of the corresponding bay-chlorinated derivatives. This steric congestion of the bay area led to helically chiral fluorophores, and chiral resolution of two...
Tetraazacoronenes and Their Dimers, Trimers and Tetramers [data]
Feb 20, 2024
Eichelmann, Robert; Ballmann, Joachim; Gade, Lutz H., 2024, "Tetraazacoronenes and Their Dimers, Trimers and Tetramers [data]", https://doi.org/10.11588/data/ZT3AHN, heiDATA, V1
Tetraazacoronenes were synthesized from bay-functionalized tetraazaperylenes by Zr-mediated cyclization and four-fold Suzuki–Miyaura cross coupling. In the Zr-mediated approach, an η4-cyclobutadiene-zirconium(IV) complex was isolated as an intermediate to cyclobutene-annulated de...
