Preparation of Nitrogen-Containing Bis(heteroaryl)iodonium Salts

Hitherto unknown nitrogen-containing bis(heteroaryl)iodonium chlorides are prepared by the reaction of the appropriate aryllithium with β-chlorovinyliodonium dichloride. The bis(heteroaryl)iodonium chlorides may be readily converted to the corresponding triflate salts via reaction with trimethylsilyl triflate.
