Merging Pyrrole with Boron into Versatile Di(2‐pyrryl)borane Building Blocks: π‐Extension, Polymerization, and Coordination

Daniel Göbel, Andreas Helbig, Alexandra Friedrich, Jonas Bachmann et autres

Conjugated di(hetaryl)boranes-particularly those of thiophene, but also of furan-have recently proven to be extremely useful building blocks for organic optoelectronic materials. The importance of the combination of boron with pyrrole, on the other hand, becomes particularly apparent when considering the well-known, versatile …

Reversible formation of tetraphenylpentalene, a room temperature stable antiaromatic hydrocarbon

Hugh J. Sanderson, Andreas Helbig, Gabriele Kociok‐Köhn, Holger Helten et autres

A rare example of a small, easily synthesisable hydrocarbon which can reversibly switch between aromatic and anti-aromatic states without any skeletal or conformational changes is reported.

The coming of age: Understanding and tuning the electronic structure of pentalenides

Niko A. Jenek, Andreas Helbig, Stuart M. Boyt, Shaun B. Reeksting et autres

Ever since its first report over 60 years ago the 10π dianionic hydrocarbon pentalenide and its intriguing organometallic chemistry has remained a rare curiosity due to the exceptional difficulty of precursor synthesis and associated limitations in ligand design. Here we report the …
