Abstract
1, 1′-Biphenyl-2-yl isocyanide dichloride and dibromide undergo unprecedented intramolecular Friedel–Crafts type cyclisation reactions catalysed by various Lewis acids affording useful synthetic methods for otherwise difficult to access 6-chloro-and 6-bromo- phenanthridines; nucleophilic displacement reactions of th
