摘要：
The reaction of tricyclohexylphosphine with the S-based palladacycle [{Pd(mu-OAc)(kappa(2)-S, C-C6H4CH2SMe)}(2)] gives several products, regardless of stoichiometry, one of which, [Pd(kappa(1)-OAc)(eta(1)-C6H4CH2SMe)(PCy3)(2)], has been characterised crystallographically. Despite this, catalysts formed in situ from di- and tri-alkylphosphines and [{Pd(mu-OAc)(kappa(2)-S, C-C6H4CH2SMe)}(2)] show excellent activity in the Suzuki coupling of a range of deactivated, non-activated and activated aryl chloride substrates.
