Scheme [3] and Table [3] display the results of the reactions of various benzyl bromides, which have a substituent at the 4-position, with TMSCN and AgClO 4 . Each gave good yields of the corresponding isocyanides. The desired conversion was not affected by the halogen and acyloxy substituents on the ring (Table [3] , entries 1-3). On the other hand, substrates having an alkoxy group as a substituent, like 4-methoxybenzyl or 4-benzyloxybenzyl bromides, afforded ...
