Organometallic compounds have acquired considerable importance in carboncarbon bond forming reactions. 1., and In particular, organoindium reagents have attracted much attention due to their compatibility with many common organic functional groups (eg R-OH, CO 2 R) and stability under aqueous conditions. Allyl indium reagents, 2., and generated in situ from allyl halides and indium metal, react with various electrophiles, such as carbonyl compounds, ...
