Scandium-Catalyzed Syndiospecific Chain-Transfer Polymerization of Styrene Using Anisoles as a Chain Transfer Agent

open access: yes, 2016
The polymerization of styrene in the presence of various anisole derivatives has been examined by using the half-sandwich scandium diamino­benzyl complex (C5Me4SiMe3)­Sc­(CH2C6H4NMe2-o)2 with borate [Ph3C]­[B­(C6F5)4].

Concerning Restricted Rotations in Pyridinyl Anisoles and Pyridinyl Phenols Bearing Saturated Handles, and Their Solid State Structures

open access: yesTetrahedron Letters, 2014
International audienceThe variable-temperature ("dynamic") NMR measurements of series of pyridinyl anisoles and pyridinyl phenols each of them bearing ortho, ortho' handles of various lengths at oxygenated ring lead to the following results: (i) at room ...

Isobaric (vapour+liquid) equilibria for three binary systems (toluene+anisole, n-butylbenzene+anisole, and guaiacol+anisole) at 101.33kPa

Fluid Phase Equilibria, 2014
Abstract Bio-oil, derived from biomass flash pyrolysis, has been recognized as an important renewable resource for resolving the current energy crisis. However, the pyrolysis oil consists of complicated composition and has some undesired properties, including acidity, relatively high viscosity, limited thermal stability, low heating value, which ...

Mechanisms and Origins of Regioselectivity in Rare-Earth-Catalyzed C-H Functionalization of Anisoles and Thioanisoles.

Inorganic Chemistry
The direct catalytic C-H functionalization of aromatic compounds such as anisoles and thioanisoles is of great interest and significance. However, achieving precise regioselectivity remains a major challenge.

Isotopomeric Conformational Change in Anisole–Water

Angewandte Chemie, 2005
The deuteration of water produces a conformational change in the Anisole×××Water complex, as shown by the scheme. The value of the q angle decreases from 138 to 128°, while the secondary interaction O×××HMe is replaced by the O×××HPh one.

A Raman spectroscopic study of the low-frequency vibrations in anisole and anisole-d3

Journal of Molecular Structure, 1977
Abstract Low-frequency Raman spectra of solid anisole and of solid anisole- d 3 have been recorded at 130 K. The phenyl torsion observed at 148 cm −1 is shifted to 133 cm −1 upon deuteration of the methyl group. The twofold torsional barriers calculated from these frequencies are 4033 ± 110 cm −1 and 4094 ± 123 cm −1 indicating that coupling to

Synthesis and Odour Thresholds of Mixed Halogenated Anisoles in Water

open access: yesWater Science and Technology, 2004
Earthy-musty off-flavour compounds in water samples are usually associated with the presence of geosmin and 2-methylisoborneol. However, the presence of 2,3,6- and 2,4,6-trichloroanisoles or other halogenated anisoles can impart objectionable tastes and ...

Homogeneous Pyrolysis of Anisole

Russian Journal of Applied Chemistry, 2001
Homogeneous pyrolysis of anisole in argon (1 : 25 volume ratio) at 750-900°C and contact time of 1.5-4.5 s was studied. The conversion and group composition of the tar and component composition of the gaseous pyrolysis products, phenols, and hydrocarbons were determined; asphaltenes and neutral oxygen-containing compounds were characterized.

Microwave spectrum of anisole

Journal of Molecular Structure, 1986
Abstract The microwave spectrum of the normal isotopic species of anisole was observed in the frequency ranges 8–18 and 26.5–40 GHz. Rotational constants were obtained for the ground vibrational state and the excited states of the torsional vibration of the phenyl group.

Dielectric Studies. IX. Relaxation Processes of Anisole- and Fluorine-Substituted Anisoles

The Journal of Chemical Physics, 1966
The dielectric constants and losses at wavelengths of 0.428, 0.860, 1.249, 1.850, and 3.220 cm and the static dielectric constant at 149.9 m have been measured for methoxypentafluorobenzene, pentafluorobenzene, trifluoromethoxybenzene, and anisole in cyclohexane solutions at 25°C. Measurements were also carried out on trifluoromethoxybenzene in decalin
