The complexes trans- (R=Ph, 1; or C6H4Me-p, 2) and trans- 3 have been prepared by reactions of trans- or trans- with allyl aryl sulphides.Complex 1 reacts with various organic halides such as allyl chloride, benzyl bromide and methyl iodide to give allyl phenyl sulphide and methyl phenyl sulphide, respectively; trans- (X=Cl, 4; B3, 5; or I, 6) were isolated from the reaction mixtures.The complexe trans- also reacts with allyl chloride to give allyl phenyl ether together with complex 4.The structure of complex 5 has been determined by X-ray crystallography: orthorhombic, space group Pbca with a=12.306(3), b=20.078(5), c=11.753(2) Angstroem, Z=8, R=0.036 and R'=0.042.It has a square-planar co-ordination around the palladium centre.The reaction of allyl chloride with complex 1 in toluene obeys first-order kinetics in the concentrations of both allyl chloride and 1.
