Abstract

Various substituted benzylic manganese chlorides were prepared by insertion of magnesium turnings in the presence of MnCl2 center dot 2LiCl in THF at -5 degrees C within 2 h. These benzylic manganese reagents underwent smooth cross-couplings with various functionalized alkenyl iodides, bromides, and triflates or iodoacrylates in the presence of 10 mol % FeCl2 at 25 degrees C for 1-12 h. Mechanistic studies showed that benzylic manganese halides produced, in the presence of FeCl2, a very reactive iron ate complex.
