a-Lithionitriles add to benzynes to give N-lithiobenzocyclobutenamines in a two-step process. The intermediate aryllithiums can be trapped prior to cyclization with iodobenzene or 2,6-dimethoxyiodobenzene to form iodine-ate complex intermediates which fragment preferentially to 2-(a-cyanobenzyl)iodo
