1 Synthesis, (7), 1195-1199; 2006 CASREACT Abstract Deactivated arenes were mono- or diiodinated with strong electrophilic I+ reagents, which were prepd. from NaIO4 and either I2 or KI in concd. H2SO4 (?5 wt%). In general a small excess (1.1/1.5 equiv) of the dark brown iodinating soln. was used (for nitrobenzene 2 equiv. were required). The iodinations were conducted at 25-30?within 1-2 h using either a 'direct' or an 'inverse' method of arom. iodination to give mono- or diiodinated pure products in 31-91% optimized yields. 2 Journal of Organic Chemistry (2002), 67(24), 8622-8624.
