摘要:
A highly selective intramolecular thiopalladation has been achieved by the treatment of o-SiVeC(6)H(4)C equivalent to CC(CF3)(=N-4-OCH3C6H4), 1, with PdCl2(PhCN)(2) in THF at 0 degrees C to afford [(C8H4S-3-) C(CF3) (=N-4-OCH3C6H4) Pd(mu-Cl)](2), 4. The mechanistic implications of the results with the aid of low-temperature H-1 NMR and ATR-IR spectroscopy are discussed.
