Reactivity of functionalized halo-derivatives with transition metal complexes. Synthesis and x-ray diffraction study of[Ph3P(CH2CH2COCH3)]+[PdCl3(PPh3)]- obtained by reaction of trans-[PdCl2(PPh3)2] with CH3COCH2CH2Cl

[PdCl3(PPh3)]-[Ph3P(CH2CH2C(O)CH3)]+ (I) was prepd. by reacting trans-[PdCl2(PPh3)2] with CH3C(O)CH2CH2Cl in boiling EtOH. The IR spectrum of I shows a band of strong intensity at 1717 cm-1 for (C:O) and bands attributable to (Pd-Cl) at 343 (s), 301(w) and 277(m) cm-1. I crystallizes in the monoclicic space group P21/n with a 18.849(9), b 21.301(9), c 9.156(7) Å, 92.8(1)°, and Z = 4. Full-matrix least-squares refinement converged at R = 0.063 (Rw = 0.055). The anion [PdCl3(PPh3)]- has approx. square planar geometry. The cation [Ph3P(CH2CH2C(O)CH3)]+ shows the usual angular distortions from the tetrahedral value at the Ph atom.
