Iodine complex organic compound effects

It was realized long ago that a number of organic compounds can obscure the blue reaction.97 This effect is caused by the formation of inclusion complexes by such compounds. Hence, the iodine reaction is widely used as the test for complexation of starch, mainly amylose, with many organic...

Hypervalent iodine oxidations of organic substrates can be effectively catalyzed by salts and complexes of gold [757-760]. For example, direct acetoxylation of electron-rich aromatic compounds 648 can be performed with (diacetoxyiodo)benzene in the presence of catalytic amounts of AuCb (Scheme 3.256) [757].
