摘要：

(Chemical Equation Presented) Captured and surrounded by C: A strongly σ-donating C,C ligand and an allyl ligand surround the palladium center in the complex shown in the scheme. The chelate, with three different types of carbon atoms, is soluble and stable in water and readily accessible on a multigram scale. It serves as the precursor to an efficient catalyst for Tsuji-Trost allylic substitution. Tf=trifluoromethanesulfonyl. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
