AldehydesP 0170 Chiral Counteranions in Asymmetric Transition-Metal Catalysis: Highly Enan-

tioselective Pd/Broensted Acid-Catalyzed Direct α-Allylation of Aldehydes. — TRIP acts both as a proton source and, in its deprotonated form, as counteranion/ligand for the cationic π-allyl-Pd intermediate. The products are obtained after acidic work-up. — (MUKHERJEE, S.; LIST*, B.; J. Am. Chem. Soc. 129 (2007) 37, 11336-11337; MPI Kohlenforsch., D-45470 Muelheim/Ruhr, Germany; Eng.) — Nuesgen
