Hfaiedh, Anoir; Ben Ammar, Hamed; Soule, Jean-Francois; Doucet, Henri published an article in 2017, the title of the article was Palladium-catalyzed regioselective C-H bond arylations at the C3 position of ortho-substituted fluorobenzenes.Computed Properties of 321-28-8 And the article contains the following content:

The influence of an ortho-substituent on fluorobenzene derivatives for palladium-catalyzed C-H bond arylation has been explored. In the presence of 2-bromo, 2-chloro and 2-methoxy substituents, the reaction proceeds nicely using a diphosphine-palladium catalyst and potassium acetate/dimethylacetamide (PivOK/DMA) as the catalytic system. In all cases, a regioselective arylation at the other ortho-position to the fluorine atom (C3) was observed A variety of electron-withdrawing substituents on the aryl bromide coupling partner, such as formyl, nitro, nitrile, and also heteroaryl bromides, was tolerated. Moreover, tri(hetero)aryl derivatives containing a fluorobenzene as the central unit have been prepared from 2-bromofluorobenzene through palladium-catalyzed-successive C-H bond (hetero)arylations. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Computed Properties of 321-28-8

On March 15, 2022, De Flaviis, Riccardo; Mutarutwa, Delvana; Sacchetti, Giampiero; Mastrocola, Dino published an article.Synthetic Route of 91-16-7 The title of the article was Could environmental effect overcome genetic A chemometric study on wheat volatiles fingerprint. And the article contained the following:

A deeper knowledge of the causes of volatile organic compounds (VOCs) variance in wheat is crucial for quality improvement and control of its derivatives The VOCs profile of common and durum wheat kernels grown in different fields sited at different altitudes over two years was analyzed and 149 compounds were identified by gas chromatog.-mass spectrometry. Principal component anal. evidenced that the year of cultivation was the highest source of VOCs variance. The effects of wheat origin, as described by the cultivation site, its elevation, and species were further investigated by PLS-DA, that permitted to correctly classify wheat of different origin on the basis of its VOCs profile. The importance of the different effects was investigated by multidimensional test and resulted: year of cultivation > field of cultivation > species > altitude. Findings suggest that environmental conditions are more important than species in the determination of the VOCs variance of wheat. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Synthetic Route of 91-16-7

On March 19, 2020, Bergmann, Katrina; van Wijngaarden, Jennifer published an article.HPLC of Formula: 321-28-8 The title of the article was Rotational Spectroscopic and Ab Initio Investigation of the Rotamer Geometries of 2-Fluoroanisole and 3-Fluoroanisole. And the article contained the following:

The rotational spectra of 2-fluoroanisole and 3-fluoroanisole were investigated using Fourier transform microwave spectroscopy in the 4-26 GHz range. Assigned transitions correspond to the lowest energy rotamer for 2-fluoroanisole which has the O-CH3 group directed away (anti) from the fluorine substituent whereas for 3-fluoroanisole, the spectrum is consistent with the presence of two rotamers arising from syn and anti orientations of the methoxy moiety relative to fluorine. Ab initio calculations at the MP2/cc-pVTZ level were used to estimate the equilibrium (re) geometries of the three observed rotamers. Their assignments were confirmed through the observation of the rotational transitions of eight minor isotopologues (13C and 18O) in natural abundance for each species. The mass dependence (rm(1)) structures derived using the exptl. determined rotational constants compare favorably with the ab initio estimates The resulting sets of geometric parameters suggest that the aromatic ring backbone is distorted by the introduction of the angular methoxy substituent, with a tendency to induce bond length alternation around the ring, and by the electron withdrawing effects of fluorine. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).HPLC of Formula: 321-28-8

On June 3, 2015, Cho, Hee Yeon; Scott, Lawrence T. published an article.Application In Synthesis of 1-Fluoro-2-methoxybenzene The title of the article was Oxidative cyclotrimerization of unsaturated compounds with DDQ and triflic acid: An efficient synthetic route to triply-fused benzene rings. And the article contained the following:

Intermol. oxidative cyclotrimerization reactions of alkenes and aromatic compounds with DDQ and trifluoromethanesulfonic acid are described. Scholl-type oxidation reactions involving alkenes have not previously been demonstrated. Moreover, the DDQ/acid system has never been used for intermol. oxidative cyclization reactions. This convenient, metal-free reagent system (DDQ/TfOH) is advantageous with respect to metal-based Scholl-type oxidants because it eliminates the possibility of halogenation of aromatic compounds as a competing side reaction.
