Abstract
The reactions of the title ylide \(C6H5)(3)PCHCOC6H4OCH3)\ (MBPPY)
with mercury(II) chloride and mercury(II) bromide in equimolar ratios
using methanol as the solvent produces crystals of (MBPPY) (.)
HgBr2(2) (1) and (MBPPY) (.) HgBr2(2) (2), respectively. Single
crystal X-ray analyses reveal the presence of centrosymmetric dimeric
structures containing the ylide and HgX2 (X = Cl or Br) in both cases.
The IR and NMR data of the product (MBPPY) (.) HgI2(2) (3), formed
by the reaction of mercury(II) iodide with the same ylide, are similar
to those of 1 and 2. Analytical data indicate a 1:1 stoichiometry
between the ylide and Hg(ll) halide in each of the three products. (C)
