摘要：

Phosphorus and arsenic keto-stabilized ylides (APPY, CMPPY, BPPY, BCyPY-OMe, APAsY, CMPAsY, BPAsY) react with Zeise's salt to give the corresponding monosubstituted Pt(II) complexes trans-[PtCl2(eta(2)-C2H4)(ylide)] (1-7). The bis-ylide complexes trans-[PtCl2(ylide)(2)] (8-12) and trans-[PtCl2(ylide)(ylide')] (13-17) can be prepared by reaction of 1-7 with the corresponding ylides. Upon heating complex 8 trans-{PtCl2[C(H)(PPh(3))COCH3](2)} in THF a cyclization reaction occurred to give {PtCl2[C(H)COCH3(PPh(2)-o-C6H4)]}[Ph(3)PCH(2)COCH(3)] (18). The molecular structure of compound 18 was determined by X-ray diffraction. The molecule consists of a metallic anion and a phosphonium counterion. Compound 18 crystallizes in the monoclinic space group P2(1)/c with unit cell parameters a=13.855(3), b=14.242(3), c=20.173(4) Angstrom, beta=109.31(5)degrees, Z=4.
