【 摘 要 】

The complexation behavior of the ¥á-ketostabilized phosphorus ylides Ph3P=CHC(O) C6H4-X (X=Br, Ph) towards the transition metal ions mercury (II) and Silver (I) was investigated. The mercury(II) complex {HgX2 [Y]} 2 (Y1=4-bromo benzoyl methylene triphenyl phosphorane; X=Cl(1), Br(2), I(3), Y2=4-phenyl benzoyl methylene triphenyl phosphorane; X=Cl(4), Br(5), I(6)) have been prepared from the reaction of Y1 and Y2 with HgX2 (X=Cl, Br, I) respectively. Silver complexes [Ag(Y2) 2] X(X=BF4(7), OTf(8)) of the ¥á-keto-stabilized phosphorus ylides (Y2) were obtained by reacting this ylide with AgX (X=BF4, OTf) in Me2CO. The crystal structure of complexes (1) and (4) was discussed. These reactions led to binuclear complexes C-coordination of ylide and trans-like structure of complexes [Y1HgCl2]2. CHCl3 (1) and [Y2HgCl2]2 (4) is demonstrated by single crystal X-ray analyses. Not only all of complexes have been studied by IR, 1H and 31P NMR spectroscopy, but also complexes 1-3 have been characterized by 13CNMR.
