Ehjeij, Daniel; Rominger, Frank; Bunz, Uwe; Freudenberg, Jan; Müllen, Klaus, 2024, "Thermolysis of Biphenylene toward Cyclo-ortho-phenylenes [data]", https://doi.org/10.11588/data/AYVNYK, heiDATA, V1
The solvent and catalyst free thermolysis of biphenylenes at 350 °C furnishes [n]cyclo-ortho-phenylenes ([n]COPs, n=4–10) in one step and in high yields. At 400 °C biphenylene dimerizes into tetraphenylene, but lower reaction temperatures produce cyclooligomers. If suitably subst... |

Fuchs, Kathleen; Dr. Rivero, Samara M.; Weidlich, Anna; Dr. Rominger, Frank; Israel, Noel; Dr. Popov, Alexey A.; Prof. Dreuw, Andreas; Dr. Freudenberg, Jan; Prof. Casado, Juan; Prof. Bunz, Uwe, 2023, "Dimerization of a Reactive Azaacene Diradical: Synthesis of a Covalent Azaacene Cage [Data]", https://doi.org/10.11588/data/QO118B, heiDATA, V1
Two series of regioisomeric dicyanomethylene substituted dithienodiazatetracenes with formal para- or ortho- quinodimethane subunits were synthesized and characterized. Whereas the para-isomers (p-n, diradical index y0=0.01) are stable and isolable, the ortho-isomer (y0=0.98) dim... |

Maier, Steffen, 2023, "Substituted Cyclopentannulated Tetraazapentacenes [data]", https://doi.org/10.11588/data/AUTKBW, heiDATA, V1
Brominated pentannulated dihydrotetraazapentacenes were prepared by gold- or palladium-catalyzed 5-endo-dig cyclization of TIPS-ethynylated dihydrotetraazaacenes (TIPS = triisopropylsilyl). Post-functionalization was demonstrated by Sonogashira alkynylation and Rosenmund-von Brau... |
