| Description |
|
| 2,2,6,6-tetramethyl-4-piperidone is an organic compound with the formula OC(CH2CMe2)2NH (where Me = CH3). It is a colorless or white solid that melts near room temperature. The compound is an intermediate in the preparation of 2,2,6,6-tetramethylpiperidine, a sterically hindered base and precursor to the reagent called TEMPO. Triacetonamine is formed by the poly-aldol condensation of acetone in the presence of ammonia and calcium chloride. |
