| Popis: | The title compound, C42H72N2O5, a hindered amine light stabiliser (HALS) with the trade name Tinuvin 144 was prepared from bis(1,2,2,6,6-pentamethylpiperidin-4-yl) 2-butylmalonate and 2,6-di-tert-butyl-4-[(dimethylamino)methyl]phenol using lithium amide as a catalyst. In the molecule, both piperidine rings adopt chair conformations. In the crystal, inversion dimers linked by pairs of O—H...O hydrogen bonds occur. |
