It also is generated by ketonization of pivalic acid and acetic acid or acetone over metal oxide catalysts. Pinacolone - Wikipedia Finally Butlerov in 1873 came up with the correct structures after he independently synthesised the compound trimethylacetic acid (Pivalic) which Friedel had obtained earlier by oxidizing with a dichromate.
