Synthesis and characterization of labile ylide of 1-(p-tolyl)-2-(tri-p-tolylphosphoranylidene)ethanone and its related complexes with mercury(II) halides

Abstract

The novel αphosphorus labile ylide of 1(ptolyl)2(triptolylphosphoranylidene)ethanone (PTTPPY) is prepared by the reaction of 2bromo1(ptolyl)ethanone with triptolylphosphine in chloroform as solvent. The complexes of the type [HgX 2 (ptolyl) 3 PCHCOC 6 H 4 CH 3 )] (X = Cl, Br and I) are prepared by the reaction of title ylide with mercury(II) halides in good yields, using methanol as solvent. The final products were characterized by IR, 1 H, 13 C, 31 P NMR spectroscopic methods and microanalysis.
