Abstract
Pd(CH 2CHPh)(PME 3) 2, prepared in situ by reaction of PdEt 2(PMe 3) 2 with styrene, reacts with allyl phenyl sulfide to give (Me 3P) 2Pd 2(μ-η 3-C 3H 5)(μ-SPh) ( 1). Complex 1 has been characterized by means of NMR ( 1H, 13C, and 31P) spectroscopy as well as X-ray crystallography. Space group P2 1/ n, a = 11.662(10, b = 17.898(2), C = 9.849(2) Å, β = 91.22(1)°, Z = 4, R = 0.049, and Rw = 0.050. The molecule has a bridging allyl ligand which coordinates symmetrically to two palladium centers. The distance between the palladium atoms (2.613(1) Å) indicates the presence of PdPd bonding in the molecule. Reaction of 1 with CO gives allyl phenyl sulfide.
