| Abstract: | The interaction of Ph2BOBu with 4-amino-4-(2-pyridyl)-3-buten-2-one, 3-amino-1-(2-pyridyl)-2-buten-I-one, and 1-(2-pyridyl)butan-1,3-dione was investigated. The 5- or 6-membered chelates withN,O- orN,N-coordination of boron are formed depending on the pyridine-containing ligand structure. These complexes are capable of mutual transformation in solutions.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 3, pp. 710–714, March, 1996. |
