A Novel Initiator of [5-(benzyloxy)-4-oxo-4H-pyran-2-yl]methyl-2-bromo-2-methylpropanoateas in Atom Transfer Radical Polymerization of Styrene and Methyl Methacrylate
A novel nano-initiator containing kojic acid moiety, [5-(benzyloxy)-4-oxo-4H-pyran-2-yl)methyl-2-bromo-2-methylpropanoate was synthesized by the reaction of 5-(benzyloxy)-2-(hydroxymethyl)-4H-pyran-4-one with 2-bromoisobutyryl bromide in triethylamine and used as initiator in the atom transfer radical polymerization (ATRP) of styrene and methyl methacrylate in the presence of Cu(0)/CuCl2and N,N...
متن کامل3-(4-{3,3,4,4,5,5-Hexafluoro-2-[5-(3-methoxyphenyl)-2-methyl-3-thienyl]cyclopent-1-enyl}-5-methyl-2-thienyl)benzonitrile
The title compound, C(29)H(19)F(6)NOS(2), is a new unsymmetrical photochromic diarylethene derivative with different meta-phenyl substituents. The distance between the two reactive (i.e. can be irradiated to form a new chemical bond) C atoms is 3.501 (4) Å; the dihedral angles between the mean plane of the main central cyclo-pentene ring and the thio-phene rings are 47.7 (5) and 45.1 (2)°, and ...
متن کاملSynthesis, Reactions and Antioxidant Activity of 5-(3', 4'-dihydroxy-tetrahydrofuran-2'-yl)-2-methyl-3-carbohydrazide
In this manuscript, we describe the synthesis of the carbohydrazide 2. Acid-catalyzed condensation with several carbonyl compounds to afford the corresponding carbohydrazide derivatives 3-12. Their acetylation afforded the corresponding acetyl derivatives 13-22. Oxidative cyclization of O-acetyl derivatives 19-22 afforded the corresponding 1,3,4-oxadiazole derivatives 23-2...
متن کامل2-Chloro-5-methyl-3-nitropyridine
The title compound, C(6)H(5)ClN(2)O(2), crystallizes with two independent mol-ecules in the asymmetric unit. Inter-molecular C-H⋯O hydrogen bonds stabilize the crystal structure.
متن کاملMethyl 5-bromo-2-chloropyridine-3-carboxylate
The title compound, C(7)H(5)BrClNO(2), crystallizes with two independent molecules in the asymmetric unit. In the absence of classical inter-molecular inter-actions, the crystal structure exhibits relatively short inter-molecular Br⋯O distances [3.143 (9) and 3.162 (9)Å].
