Iridium-catalyzed enantioselective intramolecular hydroarylation of allylic aryl ethers devoid of a directing group on the aryl group was written by Ohmura, Toshimichi;Kusaka, Satoshi;Suginome, Michinori. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2021.Name: Chlorobis(ethylene)iridium(I) dimer This article mentions the following:
Iridium/(S)-DTBM-SEGPHOS-catalyzed intramol. hydroarylation of allylic aryl ethers RC6H4OCH2C (=CH2)(R1) (R = H, 2-Me, 3-OMe, 4-F, etc.; R1 = H, Me, OTBS) was described. The reaction eliminates the structural requirement from the aryl group, affording 2,3-dihydrobenzofurans I (R2 = H, 7-Me, 6-OMe, 5-F, etc.) bearing a stereogenic carbon center at the C3 position with up to 99% enantiomeric excess. In the experiment, the researchers used many compounds, for example, Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1Name: Chlorobis(ethylene)iridium(I) dimer).
Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Name: Chlorobis(ethylene)iridium(I) dimer
