The decomposition of primary, secondary and tertiary alkylhypochlorites induced by ferrous and other one-electron oxidizable metal ions leads to δ-chloro alcohols in yields of 34–76%. In decomposition of tertiary alkylhypochlorites, β-fragmentation competes with intramolecular δ-chlorination. Tertiary cycloalkyl hypochlorites containing five- or six-membered rings undergo β-cleavage giving the corresponding
Acetoin, a novel C4 platform molecule derived from a new ABE fermentation system was used as a bio-based building block for the production of liquidhydrocarbonfuels.
The invention is directed to pyridazinone compounds and pharmaceutical compositions containing such compounds that are useful in treating infections by hepatitis C virus.
