Cost efficient preparation of lead aminoalkoxides directly from lead(II) oxide

2005

Abstract The preparation of lead(II) aminoalkoxides has been demonstrated from the direct reaction of aminoalcohols with lead(II) oxide. The denticity of the aminoalcohols determined the facility of the reactions, the rate increasing with the number of hydroxyls. Thus, [Pb(dmae)2], 1, [Pb(mdea)]∞, 2, and [Pb(teaH)]2, 3 (dmaeH = dimethylaminoethanol, mdeaH2 = N-methyldiethanolamine, and teaH3 = triethanolamine) have been prepared in high yields and characterized by 1H and 13C NMR. The X-ray crystal structure analyses of 2 and 3 are described.
