Synthesis of Biphenylenes and Their Higher Homologues by Cyclization of Aryne Derivatives

AngewchemSynthesis of Biphenylenes and Their Higher Homologues by Cyclization of Aryne Derivatives: This investigation demonstrates that a series of biphenylenes can be easily prepared from their corresponding halobiphenyls by the cyclization of in  situ generated 2′,3′‐didehydro‐2‐lithiobiphenyls at...
