A Rh-catalyzed reaction of silacyclobutanes (SCBs) with unactivated alkynes has been developed to form silacyclohexenes with high chemoselectivity. Good enantioselectivity at the stereogenic silicon center was achieved using a chiral phosphoramidite ligand. The resulting silacyclohexenes are useful scaffolds for synthesizing structurally attractive silacyclic compounds The experimental part of the paper was very detailed, including the reaction process of (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene(cas: 189518-78-3Synthetic Route of C24H20I2O4)
(R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene(cas: 189518-78-3) belongs to organic iodides. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.Iodo alkanes participate in a variety of organic synthesis reactions, which include the SimmonsSmith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Synthetic Route of C24H20I2O4
