“…It has gained great importance as a promising alternative to toxic heavy metal oxidants, such as Pb(IV), Tl(III), and Hg(II) because of its low toxicity, high stability, and easy handling (Stang and Zhdankin, 1996;Stang, 2002, 2008;Zheng et al, 2014;Yoshimura and Zhdankin, 2016). Diaryliodonium salts (Ar 1 Ar 2 I + X − ), which have two aryl groups and one counter-anion on the trivalent iodine atom, represent one of the most useful classes of hypervalent iodine(III) compounds (Merritt and Olofsson, 2009;Yusubov et al, 2011;Aradi et al, 2016;Fañanás-Mastral, 2017;Stuart, 2017). Due to the highly electron-deficient nature of the iodine(III) center in diaryliodonium salts and the excellent leaving-group ability of the iodobenzene group, they serve as highly reactive arylating agents toward a wide range of nucleophiles, even under metalfree conditions.…”
