Kirschbaum, Tobias; Rominger, Frank; Mastalerz, Michael, 2023, "Synthesis of a Benzotrisazulene via Trioxobenzotrisazulene [data]", https://doi.org/10.11588/data/JE8LF7, heiDATA, V1
A benzotrisazulene was synthesized on the basis of a truxene precursor by a series of Suzuki–Miyaura reactions via the intermediate trisoxo compound. The latter occurs in two forms (syn and anti), and the syn forms porous crystals. |

Ahrens, Lukas; Rominger, Frank; Freudenberg, Jan; Bunz, Uwe H. F., 2023, "Etheno-bridged Azaacene Spiro Dimers [data]", https://doi.org/10.11588/data/L8NDRO, heiDATA, V1
We present the synthesis of two sets of spiro-connected azaacene dimers. Their geometry and electronic coupling are critically determined by a secondary linker, i.e. an etheno- and an ethano-bridge.The core fragment of the etheno-bridged dimer corresponds to a conformationally lo... |

The transition-metal catalyzed cyclization of bissilylethynylated N,N’-dihydro¬tetra¬aza¬pentacene (TIPS-TAP-H2) into bissilylated cyclo¬penta¬[fg,qr]¬pentacenes is reported. Depending on the catalyst either none, one or two silyl groups migrate and change their positions in the... |
