Preparation and characterization of mercury [II] -keto stabilized ylides complexes

Two new series of mercury [II]-Ylides Complexes were prepared from phosphoranes and sulphuranes with mercury [II] chloride. The complexes have the general formula [Hg L C1[2]] and [Hg L[2] G1[2], where L = bidentate phosphorane or sulforane ligands. The prepared complexes were characterized by elemental analysis and conductance measurements. The IR-spectra of the complexes showed that both C=-O and S or ph[3]P coordinate to the central mercury [II] ion on complex formation. Electronic and 1H-NMR spectra of the complexes were also made use of to study the ligated groups around the central mercury [II] ion

Spectroscopic studies of some anilide compounds derived from ethyl benzoyl acetate

The electronic absorption spectra of some anilide compounds derived from ethyl benzoyl acetate are investigated in organic solvents of varying polarities and buffer solutions of different pH. The behavior in the latter case is utilized in addition to the potentiometric technique for calculating pKa of the enolic OH group. The important bands the IR spectra and H-NMR signals are assigned and discussed in relation to molecular structure
