An air-stable cationic iridium hydride as a highly active and general catalyst for the isomerization of terminal epoxides.
We describe the use of an air-stable iridium hydride catalyst for the isomerization of terminal epoxides into aldehydes with perfect regioselectivity. The system operates at low loadings of catalyst (0.5 mol%), is highly practical, scalable, and tolerates functional groups that would not be compatible with Lewis acids typically used in stoichiometric amounts. Evidence for a rare hydride mechani...

متن کاملMutagenicity of aliphatic epoxides.
The mutagenicity of 17 aliphatic epoxides was determined using the specially constructed mutants of Salmonella typhimurium developed by Ames. The activity of these epoxides together with those reported in the literature as mutagens in strains TA100 and TA1535 depended on the degree of substitution around the oxirane ring. Monosubstituted oxiranes were the most potent mutagens in both strains. 1...
