Direct functionalization of the benzylic C?H bond of diarylmethanes is an important strategy for the synthesis of diarylmethine-containing compounds. However, the methods developed to date for this purpose require a stoichiometric amount (usually more) of either a strong base or an oxidant. Reported here is the first catalytic benzylic C?H bond addition of diarylmethanes to styrenes and conjugated dienes. A potassium zincate complex, generated from potassium benzyl and zinc amide, acts as a catalyst and displays good activity and chemoselectivity. Considering the atom economy of the reaction and the ready availability of the catalyst, this reaction constitutes a practical, efficient method for diarylalkane synthesis.

The addition of reactive carbanions to tricarbonyl(η4-1,3-diene)iron()) complexes proceeded at -78 deg C to give putative triacarbonyl(η1,η2-but-3-en-1-yl)iron(0) anion complexes and at 25 deg C to produce postulated triabarbonyl(η3-allyl)iron(0) anion complexes; trapping of reactive intermediates with dioxygen produced γ,δ-unsaturated acids and allylic alcohols, respectively.Key Words: Diene iron complex; γ,δ-Unsaturated acids; Allylic alcohols.
