Iron-catalyzed addition of Grignard reagents to activated vinyl cyclopropanes
Benjamin D. Sherry and Alois Fürstner
A highly regioselective iron-catalyzed addition of branched primary, secondary or tertiary alkyl Grignard reagents to activated vinyl cyclopropanes is described, which likely proceeds by a direct addition mechanism as opposed to single electron transfer or an iron-allyl based process.
