Synthesis and Spectral Characterization of 4-Methoxybenzoylmethylenetri-p-tolylphosphorane and It's Reaction with Mercury(II) Halides

Abstract

The reaction of the 4-methoxybenzoylmethylenetri-ptolylphosphorane {(CH₃C₆H₄)₃PCHCOC₆H₄OCH₃)} (MBPTY) with mercury(II) halide in equimolar ratios using methanol as solvent have yielded [(MBPTY)·HgCl₂]₂ (1), [(MBPTY)·HgBr₂]₂ (2), [(MBPTY)·HgI₂]₂ (3). IR, ¹H, ¹³C and ³¹P NMR together with microanalysis data of the products were obtained. Analytical data indicate a 1:1 stoichiometry between the ylide and Hg(II) halide in each of the three products.
