Abstract

A variety of β-substituted alkyl halides and epoxides are reductively eliminated in high yields to alkenes by CrIIen at room temperature. The reducing agent is easily prepared in situ from chromous salts and ethylenediamine. Reductive elimination and protolytic reduction of β- substituted alkyl halides by chromous reagent proceed by similar mechanisms, and involve free radicals and alkylchromium species as intermediates. In the former process, β- ...
