CRİSTALLİK AND MOLEKULYAR STRUKTURE OF 2,2,6,6-TETRAMETİL-4-HİDROKSİ PİPERİDİN HİDROXLORİDE
The reaction of carboxymethylation and amidation of 2,2,6,6 tetramethyl-4-hydroxy piperidine with chloracetic acid and oxalyl chloride was investigated. It was shown that instead of the expected derivatives of aminoacetic acid and diamide hydrochloride the formation of 2,2,6,6-tetramethyl-4-hydroxyoxy piperidine hydrochloride takes place. The molecular and crystalic structures of obtained compound were determined.
Keywords : sterical hindered amine, chloracetik acide, oxalyl chloride, acylation, of 2,2,6,6-tetramethyl-4-hydroxy piperidine hydrochloride, X-ray structure
