• Steric effects on the formation of isolable products in the reactions of dibutyltin oxides with carboxylic acids
  作者：V.B. Mokal、V.K. Jain

  DOI：10.1016/0022-328x(92)83381-q

  日期：1992.12

  (CH3)2CH (iPr) and (CH3)3C (tBu)] in 1:1 and 1:2 stoichiometry were investigated. The products formed in these reactions were characterized by elemental analyses, IR and NMR (1H, 13C and 119Sn) data. Reactions in 1:2 stoichiometry afforded dibutyltin dicarboxylates which have six-coordinate tin atom. Steric effects of the butyl group and the R group of the carboxylate ligand play an important role in
