2,6-Di-tert-butyl-4-(methoxymethyl)phenol
The title compound, C(16)H(26)O(2), was easily obtained in high yield when 4-bromo-methyl-2,6-di-tert-butyl-phenol was reacted with methanol. There are two independent mol-ecules in the asymmetric unit. The meth-oxy group in each of the independent mol-ecules was found to be disordered, with site-occupation factors of 0.8728 (18)/0.1272 (18) and 0.8781 (17)/0.1219 (17).
متن کامل2,4-Di-tert-butyl-6-[1-(3,5-di-tert-butyl-2-hydroxyphenyl)ethyl]phenyl 4-methylbenzenesulfonate
The title compound, C(37)H(52)O(4)S, was obtained by the reaction of 6,6'-(ethane-1,1-di-yl)bis-(2,4-di-tert-butyl-phenol) and 4-methyl-benzene-1-sulfonyl chloride. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯O hydrogen bond. Two of the tert-butyl groups are disordered over two sets of sites with occupancies 0.530 (15)/0.470 (15) and 0.615 (11)/0.385 (11).
متن کامل2,6-Di-tert-butyl-4-(dimethylaminomethyl)phenol
The title compound, C(17)H(29)NO, is an important hindered phenol derivative. The asymmetric unit contains two mol-ecules. Molecules inter-act through O-H⋯N hydrogen bonds to form a tetramer arranged around a twofold rotation axis.
متن کاملDecomposition of vitamin D by the hydroperoxide formed from 2,6-di-tert-butyl-4-methylphenol during alkali saponification.
When vitamin D2 was saponified with addition of BHT in an alkaline solution, the low recoveries were observed. These were confirmed to be due to the oxidation of vitamin D2 by 2, 6-di-tert-butyl-4-methyl-4-hydroperoxy-2, 5 -cyclohexadiene-1-one formed from BHT during alkali saponification. The de composition of vitamin D2 was protected by the addition of sufficient quantities of sodium ascorbat...
متن کامل2-tert-Butyl-6-[(4-chloro-2-nitrophenyl)diazenyl]-4-methylphenol
In the title compound, C(17)H(18)ClN(3)O(3), the dihedral angle between the planes of the two benzene rings is 1.03 (7)°. The overall conformation of the mol-ecule is influenced, in part, by electron delocalization and by an intra-molecular bifurcated O-H⋯(O,N) hydrogen bonds. The O atoms of the nitro group, one of which serves as an H bond acceptor, are disordered over two sets of sites with r...
