Synthesis and X-ray study of a bis-diphenylboron chelate of 3-(diaminomethylene)pentane-2,4-dione

Article abstract of DOI:10.1007/bf01431123

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.
