Safety of (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthaleneOn October 14, 2013 ,《Asymmetric Intramolecular Hydroamination of Allenes using Mononuclear Gold Catalysts》 was published in Organometallics. The article was written by Michon, Christophe; Medina, Florian; Abadie, Marc-Antoine; Agbossou-Niedercorn, Francine. The article contains the following contents:
The intramol. gold-catalyzed asym. hydroamination of allenes was studied by screening a series of mononuclear gold(I) and (III) complexes in combination with silver salts. Among the various chiral monophosphine and diaminocarbene ligands tried, the best catalysts arose from mononuclear gold(I) complexes synthesized from BINOL-based phosphoramidite ligands. The latest were improved by addition of bulky substituents at specific positions of the BINOL scaffold. The resulting gold(I) complexes were combined with selected silver salts to afford efficient catalysts for intramol. hydroamination of allenes at room temperature or below, with good conversions and enantioselectivities. In the experimental materials used by the author, we found (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene(cas: 189518-78-3Safety of (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. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.Safety of (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene
