The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Mercury(II) complexes of β-diketones》. Authors are Nonhebel, D. C..The article about the compound:2,6-Dimethyl-3,5-heptanedionecas:18362-64-6,SMILESS:CC(C)C(CC(C(C)C)=O)=O).COA of Formula: C9H16O2. Through the article, more information about this compound (cas:18362-64-6) is conveyed.
Hg derivatives of diisobutyrylmethane and dipivaloylmethane are enolates, not cyclic derivatives like other metal β-diketones, as shown by infrared and reactions with BzCl and p-nitrobenzoyl chloride to give O-acylated β-diketones.
As far as I know, this compound(18362-64-6)COA of Formula: C9H16O2 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
