Cost efficient preparation of lead aminoalkoxides directly from lead(II) oxide
摘要:
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)](infinity), 2, and [Pb(teaH)](2), 3 (dmaeH = dimethylaminoethanol, mdeaH(2) = N-methyldiethanolamine, and teaH(3) = triethanolamine) have been prepared in high yields and characterized by H-1 and C-13 NMR. The X-ray crystal structure analyses of 2 and 3 are described. (c) 2005 Elsevier B.V. All rights reserved.
