Recommanded Product: (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthaleneOn March 6, 1998, Huang, Wei-Sheng; Hu, Qiao-Sheng; Pu, Lin published an article in Journal of Organic Chemistry. The article was 《A Highly General Catalyst for the Enantioselective Reaction of Aldehydes with Diethylzinc》. The article mentions the following:
An optically active 1,1′-binaphthyl mol., (R)-3,3′-bis(2”,4”-dihexyloxyphenyl)-1,1′-bi-2-naphthol[(R)-I], is found to be the most general catalyst for the enantioselective reaction of aldehydes with diethylzinc. This compound catalyzes the reaction of diethylzinc with a very broad range of aldehydes including ortho-, para- or meta-substituted aromatic aldehydes, linear or branched aliphatic aldehydes, and aryl or alkyl-substituted α,β-unsaturated aldehydes in 91 – <99% ees. The extremely general and high enantioselectivity of (R)-I and its easy preparation make this mol. a very practical catalyst for the synthesis of chiral alcs. After reading the article, we found that the author used (R)-3,3'-Diiodo-2,2'-bis(methoxymethoxy)-1,1'-binaphthalene(cas: 189518-78-3Recommanded Product: (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene)
(R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene(cas: 189518-78-3) 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. Recommanded Product: (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.
