Abstract

A C,N-bound palladacycle dimer has been synthesised by reaction of 2-(thiophen-2-yl)pyridine, LH, with palladium acetate in acetic acid. Characterisation by single crystal X-ray diffraction showed the palladacycle dimer, [(L)Pd(OAc)]2, to crystallise in the monoclinic space group P21/n with cell parameters a = 9.5853(1) Å, b = 19.1332(3) Å, c = 12.3889(2) Å, β = 103.732(1)°. Reaction of [(L)Pd(OAc)]2 with triphenylphosphine afforded a trans-substituted monomeric complex, [(L)PdPPh3(OAc)] which was also analysed using single crystal X-ray diffraction. [(L)PdPPh3(OAc)] crystallises in the monoclinic space group P21/c with cell parameters a = 9.4839(1) Å, b = 11.0427(2) Å, c = 26.0770(4) Å, β = 95.022(1)°.
