iron(II)-catalyzed radicalalkyl Heck-type reaction of alkyliodides with vinylarenes under mild conditions has been reported. t-Butyl peroxybenzoate (TBPB) behaves simultaneously as a radical relay initiator, a precursor for the generation of alkylradical from alkyliodides, and an oxidant to recycle iron(II)/iron(III). Unactivated primary, secondary, and tertiary alkyliodides are compatible with

The first iron-catalyzed formal cross coupling of homobenzylic methyl ethers with alkyl Grignardreagents is realized. The reaction is proposed to proceed through a sequence of dehydroalkoxylation to form the vinyl-intermediate, followed by Fe-catalyzed selective carbometalation to form a benzylic Grignardreagent.
