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... |
