Simple, mild, and efficient conditions are reported for a Pd 0-catalyzed Heck reaction that delivers high yields and selectivity for (E)-styrenyl products using electronically nonbiased olefin substrates bearing a range of useful functionality. Preliminary mechanistic studies demonstrate that the σ-donating DMA solvent is crucial for high selectivity. Further studies suggest that the catalyst distinguishes between β-hydrogens on the basis of their relative hydridic character, in contrast to previously reported PdII-catalyzed oxidative reaction conditions.
A FACILE ONE-STEP SYNTHESIS OF β,γ-UNSATURATED CABOXYLIC ACID ESTERS VIA 1,2-CARBONYL TRANSPOSITIONS OF α,β-UNSATURATED KETONES

Reaction of α,β-unsaturated ketone, 1, with lead(IV)acetate and borontrifluoride etherate in the presence of methanol yielded the β,γ-unsaturated esters, 2, in a single step procedure, at room temperature.
