In 2019,Organic Letters included an article by Jana, Sripati; Koenigs, Rene M.. Reference of 1-Chloro-3-iodobenzene. The article was titled 《Rhodium-Catalyzed Carbene Transfer Reactions for Sigmatropic Rearrangement Reactions of Selenium Ylides》. The information in the text is summarized as follows:
The rearrangement of selenium ylides is even today almost unexplored, although it would provide access to important organoselenium compounds with broad downstream applications. In this report, the first systematic study of sigmatropic rearrangement reactions of selenium ylides using a simple rhodium catalyst with catalyst loadings as low as 0.01 mol % is described. Selenium oxide pyrolysis of the rearrangement products gives access to important 1,1-disubstituted butadienes. In the experiment, the researchers used 1-Chloro-3-iodobenzene(cas: 625-99-0Reference of 1-Chloro-3-iodobenzene)
1-Chloro-3-iodobenzene(cas: 625-99-0) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine.Reference of 1-Chloro-3-iodobenzene
