Synthesis and Characterization of π‐Extended Azulenes via Nucleophilic Substitution and Intramolecular Cyclization of 5‐Alkynyl‐6‐Fluoroazulenes

ChemistryEurope, EarlyView.
A modular synthetic approach enables the preparation of azulene‐fused heterocycles via nucleophilic aromatic substitution followed by intramolecular cyclization of alkynyl fluoroazulenes. The method allows the incorporation of various heteroatoms (N, O, S, Se, and Te), leading to structurally diverse heteroannulated azulenes.

Borohydride - Oxide Isomorphism in Design of Energy Storage Materials [PDF]

Acta Crystallographica Section A Foundations and Advances, 2014
An increasing number of novel single, double and triple cation borohydrides has been structurally characterized in the last few years as hydrogen storage materials and solid state electrolytes for battery applications [1,2]. It is interesting to note that the majority of these novel metal borohydrides resemble structures of various metal oxides.
