TL;DR: In this paper, the solid phase of isolated solvate [Cu(hfac)2L]·0.5MePh, where hfac is hexafluoroacetylacetonate, consists of polymer chains inside which Dipyridine (L) acts as a bridge, linking together Cu(hfa)2 moieties by N atoms of pyridine rings.
Abstract: 4,4′-(Triaz-1-ene-1,3-diyl)dipyridine (L) and the first transition metal complex with it are synthesized. It is found that the solid phase of isolated solvate [Cu(hfac)2L]·0.5MePh, where hfac is hexafluoroacetylacetonate, consists of polymer chains inside which L acts as a bridge, linking together Cu(hfac)2 moieties by N atoms of pyridine rings. The chains, in turn, are arranged into layers by H bonds. The result shows that L can be a bridging ligand in the synthesis of new coordination polymers.

TL;DR: In this article, the authors describe the direct synthesis of polysubstituted indolo[2,1-a]isoquinoline analogues via a double C-H annulation cascade using triazene as an internally cleavable directing group.
Abstract: Indole-containing polyaromatic scaffolds are widely found in natural products, pharmaceutical agents, and π-conjugated functional materials. Often, the synthesis of these highly valuable molecules requires a multistep sequence. Therefore, a simple, one-step protocol to access libraries of polyaromatic indole scaffolds is highly desirable. Herein we describe the direct synthesis of polysubstituted indolo[2,1-a]isoquinoline analogues via a double C–H annulation cascade using triazene as an internally cleavable directing group. Evidence from HRMS and theoretical calculations suggests that an unprecedented 1,2-alkyl migration might be responsible for the in situ cleavage of the directing group. Both kinetic isotope effects and DFT calculations suggested that the alkyne insertion step is rate-limiting for the second C,N annulation reaction.
