Oxidative displacement of halogen from alkyl halides by phenyliodine(III) dicarboxylates was written by Gallos, John;Varvoglis, Anastasios. And the article was included in Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) in 1983.Reference of 3268-21-1 This article mentions the following:
The reaction of alkyl iodides with aryliodine(III) dicarboxylates gave mainly esters derived through substitution of iodine by an acyloxy group, together with, in some cases, α-iodoalkyl esters. E.g., reaction of PhI(O2CCF3)2 with Me2CHI in EtOH-free CHCl3 in the dark at room temperature for 2-8 h gave F3CCO2CHMe2, quant. Reactive bromides and chlorides reacted similarly. In the experiment, the researchers used many compounds, for example, 1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1Reference of 3268-21-1).
1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1) belongs to iodide derivatives. Organic iodides are widely used in organic synthesis. Halogenation of aromatic hydrocarbons is a very important reaction via an electrophilic aromatic substitution. Polyiodoorganic compounds are sometimes employed as X-ray contrast agents, in fluoroscopy, a type of medical imaging. This application exploits the X-ray absorbing ability of the heavy iodine nucleus.Reference of 3268-21-1
