Organomercury(II) and diorganothallium(III) derivatives of 4-acylpyrazol-5-ones
摘要:
The synthesis and characterization of four organomercury derivatives of 1-phenyl-3-methyl-4-acyl-5-pyrazolones (L), RHgL (R = Me, Ph; acyl - acetyl, benzoyl), are described. The report includes the crystal structure of one compound, PhHg[1-Ph-3-Me-4-PhCO-5-C2N2CO], which represents the first crystallographically authenticated mercury beta-diketonate bonded to the metal through oxygen, and also the first structural report on an organomercury beta-diketonate. For comparison, the two diphenylthallium derivatives of the same two pyrazolone ligands have also been prepared.
