Abstract
Reactions of title ylide, \(C6H5)(3)PCHCOC6H4C6H5)\ (BPPPY), with
mercury(II) halides in equimolar ratios in methanol yielded dinuclear
complexes (BPPPY)HgCl2(2) (1), (BPPPY) HgBr2(2) (2), and
(BPPPY)HgI2(2) (3). Reactions of BPPPY with CdCl2 in equimolar
ratios gave (BPPPY)CdCl2(2) (4). Reaction of PdCl2 with BPPPY (1/2)
in acetonitrile at room temperature gave cis/trans
PdCl2\CH(PPh3)COC6H4C6H5\(2) (5). The same reaction at reflux gave
the orthopalladated complex
Pd\CH\P(2-C6H4)Ph\(COC6H4C6H5)\(mu-Cl)(2) (6) along with the
phosphonium salt Ph3PCHCOC6H4C6H5Br. The compounds were
characterized by elemental analysis, IR-, H-1-, C-13-, and P-31-NMR
spectroscopy. Single crystal X-ray analysis of 3 reveals the
centrosymmetric dimeric structure containing the ylide and HgI2.
Crystallographic data for 3 are: crystal system, monoclinic; space
group, P 2(1)/n, a = 15.7744(7), b = 23.0288(9), c = 20.2867(9)
angstrom, beta = 112.237(3)degrees, V = 6821.4(5) angstrom(3), and Z =
1.
