Abstract
The reaction between cis-[Pd(C6F5)2(thf)2](thf = tetrahydrofuran) and benzyldimethylamine rendered cis-[Pd(C6F5)2(C6H5CH2NMe2-κC1,κN)]1, a four-co-ordinate compound containing an unusual η1arene–palladium interaction with the benzyldimethylamine acting as a bidentate chelating ligand. Complex 1 reacts with acetone, acetonitrile, dimethyl sulfoxide or CO (L) to yield cis-[Pd(C6F5)2(NMe2CH2C6H5)(L)]2–5 respectively, which do not have a η1 arene–palladium interaction. The reaction of 1 with Br–or SPMe2Ph (L′)(molar ratio 1:1) produced the complete displacement of the amine and the formation of [(F5C6)2Pd(µ-L′)2Pd(C6F5)2]n–(n= 2 or 0), and with Cl–(molar ratio 1:1) a mixture of complexes is formed. The crystal structures of compounds 1and 2 have been determined.Keywords
