Molecular Structure and Carbonylation of Ethyl(benzenethiolato)-palladium(II) Complex, trans-PdEt(SPh)(PMe3)2

Abstract X-Ray crystallography of ethylpalladium thiolato complex, trans-PdEt(SPh)(PMe3)2, shows the detailed features of the Pd–C and Pd–S bonding. Reaction of the complex with CO at 5 atm gives S-phenyl thiopropionate. The NMR spectrum of the reaction mixture under 1 atm of CO shows the presence of trans-Pd(COEt)(SPh)(PMe3)2 formed through CO insertion into the Pd–C bond.
