Synthesis and Spectral Studies of Mercury(II) Complexes of 4-Bromobenzoylmethylenetriphenylphosphorane

Abstract

The new α-phosphorus ylide of (4-bromobenzoylmethylenetriphenylphosphorane) (BBPPY) (1) is prepared by the reaction of 2,4'-bromoacetophenone with triphenyl phosphine in chloroform as solvent. The mercury(II) complexes of the type (BBPPY· HgCl₂) (2), (BBPPY·HgBr₂) (3), (BBPPY· HgI₂) (4) and (BBPPY·Hg(NO₃)₂ (5) are prepared by the reaction of BBPPY with mercury(II) halides and nitrate in moderate to good yields.
