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(η2-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)(PPh3)COCH3]2} in THF a cyclization reaction occurred to give {PtCl2[C(H)COCH3(PPh2-o-C6H 4)]} [Ph3PCH2COCH3] (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 P21/c with unit cell parameters a= 13.855(3), b= 14.242(3), c = 20.173(4) A, β= 109.31(5)°, Z=4.
