Synthesis and Multinuclear NMR Study of 4-Methylbenzoylmethylene-tri-ptolylphosphorane Ylide and its Related Complexes with Mercury(II) Halides

Abstract

The novel a-phosphorus ylide of (4-methylbenzoylmethylene- tri-p-tolylphosphorane) (MBTPPY) (1) is prepared by the reaction of 4-methylacetophenone with tri-p-tolylphosphine in chloroform as solvent. The complexes of the type (MBTPPY·HgCl₂) (2), (MBTPPY·HgBr₂) (3) and (MBTPPY· HgI₂) (4) are prepared by the reaction of MBTPPY with mercury(II) halides in moderate to good yields.
