Bis(1,2,2,6,6-penta­methyl­piperidin-4-yl) 2-butyl-2-(3,5-di-tert-butyl-4-hydroxy­benz­yl)malonate (Tinuvin 144)

The title compound, C(42)H(72)N(2)O(5), 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,...

description The title compound, C(42)H(72)N(2)O(5), 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.
