Nickel-catalyzed [4 + 2] Cycloaddition of Styrenes with Arynes via 1:1 Cross-coupling: Synthesis of 9,10-Dihydrophenanthrenes
The [4 + 2] cycloaddition of styrenes with arynes was achieved via 1:1 cross-coupling by a nickel catalyst. This protocol applies to a variety of styrenes and arynes generated in situ from o-(trime...
