摘要:
The interaction of Ph(2)BOBu with 4-amino-4-(2-pyridyl)-3-buten-2-one, 3-amino-1 -(2-pyridyl)-2-buren-1-one, and 1-(2-pyridyl)butan-1,3-dione was investigated. The 5- or 6-membered chelates with N, O- or N, N-coordination of boron are formed depending on the pyridine-containing ligand structure. These complexes are capable of mutual transformation in solutions.
