2,4,6-Tri-p-tolyl­pyridine

REACTION OF 4-METHYL- 1 2,4-TRIAZOLINE- 3,5-DIONE WITH DI AND TRI-SUBSTITUTED STYRENES S.E. Mallakpour* and G.B. Butler**

2,4,6-Triisopropylstryrene was synthesized in a single step via the Witting Reaction from the corresponding aldehyde. The reaction of three styrene's derivatives, 2,6-dimethylstyrene, 2,4,6-trimethylstyrene, and 2,4,6- triisopropylstyrene with 4-methyl-l,2,4-triazoline-3,5-dion(M eTD) was investigated. These reactions are instantaneous at room temperature and lead to the formation of 2: 1 ...

The first crystal structure of a monomeric phenoxyl radical: 2,4,6-tri-tert-butylphenoxyl radical.

Crystals of the 2,4,6-tri-tert-butylphenoxyl radical have been isolated and characterized by X-ray diffraction, and calculations have been performed that give the distribution of spin density in the radical.

Phenoxy radical detection using P NMR spin trapping

ion and subsequent deprotonation gives rise to phenoxy radicals, which play a pivotal role in lignin chemistry. Overall spin trapping systems could be powerful tools to understand the radical intermediates involved in lignin chemistry. In Table 4 our data on spin trap experiments with DIPPMPO and different phenols are shown. There are different oxidation systems for the generation of phenoxy ra...

Screening Assessment for the Challenge Phenol, 2,4,6-tris(1,1-dimethylethyl)- (2,4,6-tri-tert-butylphenol)

Crystal structures of a copper(II) and the isotypic nickel(II) and palladium(II) complexes of the ligand (E)-1-[(2,4,6-tri­bromo­phen­yl)diazen­yl]naphthalen-2-ol

In the copper(II) complex, bis-{(E)-1-[(2,4,6-tri-bromo-phen-yl)diazen-yl]naph-thalen-2-olato}copper(II), [Cu(C16H8Br3N2O)2], (I), the metal cation is coord-inated by two N atoms and two O atoms from two bidentate (E)-1-[(2,4,6-tri-bromo-phen-yl)diazen-yl]naphthalen-2-olate ligands, forming a slightly distorted square-planar environment. In one of the ligands, the tri-bromo-benzene ring is incl...
