VOLATILE ALKALI METAL BETA-KETOENOLATE COMPOUNDS

Alkali metal compounds of a number of β-ketoenols have been isolated and qualitative assessments of their volatility, thermal stability, hydrolytic stability, and extraction into organic solvents have been made. The influence of fluorine-containing and bulky substituents in the β-ketoenols is discussed. The sodium β-ketoenolate of 1-(undecafluorobicyclo[2.2.1]heptan-1-yl)-4,4,4-trifluorobutan-2,4-dione, a ligand combining a bulky and fluorine-containing group is described. © 1969.
