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.

One‐Pot Ruthenium‐Catalyzed Synthesis of Benzyl/Allyl‐Halide Substituted (dihydro)naphthalenes via Radical Benzannulation

ChemistryEurope, EarlyView.
A one‐pot protocol to synthesize reactive benzyl‐ and allyl‐halide‐substituted (dihydro)naphthalenes from 2,3‐aryl‐1,3‐butadiene substrates and halogenated alkanes has been developed, using [Cp*RuCl(PPh3)2] as the catalyst. Mechanistic studies revealed an atom transfer radical addition and radical benzannulation sequence, followed by HCl elimination ...
