After the successful synthesis of ENHIs with different N-heterocycles, the tolerance of various functional groups at the iodoarene was investigated, using the methylated C-bound triazole as a model substrate (Scheme 1 -b). Most electron withdrawing halogen-and CF 3 -substituted iodoarenes 3j-3l yielded the desired products 1j-l in good yields of 51-55%. The NO 2 -derivative yielded 1m in diminished yields. The low yield of 18% for the chlorinated salt 1n can be explained by steric effects between the substituent and the alkyne. A similar tendency was observed for the methylated derivatives 1o-p. Here, para-methylation gave a yield twice as high as the ortho-substituted salt (31% vs. 65%). The biphenyl 1q was also obtained in a good yield of 52%, so that an overall high functional group tolerance of the pseudocyclic salts could be demonstrated.
