A bis-diphenylboron chelate has been synthesized from 3-(diaminomethylene)pentane-2,4-dione through the action of (butylthio)diphenylborane and its molecular and crystal structures have been determined. The two boron -containing rings have the same six-membered skeleton but differ substantially in conformation and geometric parameters.

A method for synthesizing 3-acetyl-2-amino-4-pyridone has been suggested. The synthesis involves the condensation of dimethylformamide dimethylacetal at the NH2 group of diphenylboron chelate diacetylketene aminal followed by its intramolecular cyclization under the action of NaOMe in MeOH.
