ABSTRACT:
A process for making a sterically-hindered beta-diketone involving: (a) providing a solution comprising: (i) an ester; (ii) a base; and (iii) a solvent; (b) adding a ketone selected from the group consisting of an aromatic ketone and a hindered aliphatic ketone, to the solution, to form a condensation reaction mixture, whereby either the ester or the ketone is hindered; (c) reacting the solution with the ketone to form a sterically-hindered beta-diketone; and (d) recovering the sterically-hindered beta-diketone from the condensation reaction mixture.
