pyridinecarbaldehydes have been cyclized under very mild reaction conditions in the presence of I(2), ICl, PhSeCl, PhSCl, and p-O(2)NC(6)H(4)SCl to give the corresponding halogen-, selenium-, and sulfur-containing disubstituted isoquinolines and naphthyridines, respectively. This methodology accommodates a variety of iminoalkynes and affords the anticipated heterocycles in moderate to excellent yields. Monosubstituted
