The enolization of the non-bonded carbonyls in this case depends on the nature of substituents at positions 2 and 4 of the 1,3,5-triketone moiety. The molecular structure of one triketonate complex was confirmed by X-ray single crystal investigation.???? \\\\Expert2\\nbo\\Journal of Fluorine Chemistry\\2004, v.125, p.1137.pdf |
