A denuder-impinger system with in situ derivatization followed by gas chromatography-mass spectrometry for the determination of gaseous iodine-containing halogen species.

J. Chromatogr. A. 1210(2) , 135-41, (2008)

Reactive iodine species have been suggested to play an important role in the atmosphere (e.g. tropospheric ozone depletion, coastal new particle formation). However, there still exist major uncertainties about their atmospheric chemistry, mostly due to the la...

Ozonolysis of lignin models in aqueous solution: anisole, 1,2-dimethoxybenzene, 1,4-dimethoxybenzene, and 1,3,5-trimethoxybenzene.

Environ. Sci. Technol. 43(16) , 6275-82, (2009)

The lignin models anisole, 1,2-dimethoxybenzene, 1,4-dimethoxybenzene, and 1,3,5-trimethoxybenzene were reacted with ozone in aqueous solution, and major products were identified and quantified with respect to ozone consumption when reference material was ava...

Stereoselective glycosylations using oxathiane spiroketal glycosyl donors.

Carbohydr. Res. 348 , 6-13, (2012)

Novel oxathiane spiroketal donors have been synthesised and activated via an umpolung S-arylation strategy using 1,3,5-trimethoxybenzene and 1,3-dimethoxybenzene. The comparative reactivity of the resulting 2,4,6-trimethoxyphenyl (TMP)- and 2,4-dimethoxypheny...

Solvation of dichlorocarbene: complexation with aryl ethers.

J. Phys. Chem. A 114(1) , 209-17, (2010)

Dichlorocarbene (CCl(2)), generated by laser flash photolysis of dichlorodiazirine, formed pi- and O-ylidic complexes with aromatic ethers such as anisole, 1,3-dimethoxybenzene, 1,3,5-trimethoxybenzene, dibenzofuran, and dibenzo-18-crown-6 and with the aromat...

Use and qualification of primary and secondary standards employed in quantitative ¹H NMR spectroscopy of pharmaceuticals.

J. Pharm. Biomed. Anal. , doi:10.1016/j.jpba.2013.09.010, (2013)

Standards are required in quantitative NMR (qNMR) to obtain accurate and precise results. In this study acetanilide was established and used as a primary standard. Six other chemicals were selected as secondary standards: 3,4,5-trichloropyridine, dimethyltere...

One-electron oxidation of alcohols by the 1,3,5-trimethoxybenzene radical cation in the excited state during two-color two-laser flash photolysis.

J. Phys. Chem. A 111(10) , 1788-91, (2007)

One-electron oxidation of alcohols such as methanol, ethanol, and 2-propanol by 1,3,5-trimethoxybenzene radical cation (TMB*+) in the excited state (TMB*+*) was observed during the two-color two-laser flash photolysis. TMB*+ was formed by the photoinduced bim...

Acute exacerbation of pain in irritable bowel syndrome: efficacy of phloroglucinol/trimethylphloroglucinol. A randomized, double-blind, placebo-controlled study.

Aliment. Pharmacol. Ther. 25(9) , 1115-23, (2007)

Abdominal pain is the predominant symptom in irritable bowel syndrome patients. Phloroglucinol and its methylated derivative are antispasmodic agents acting on smooth muscle.To evaluate the efficacy of phloroglucinol/trimethylphloroglucinol on pain intensity ...

Silver(I)-catalyzed deprotection of p-methoxybenzyl ethers: a mild and chemoselective method.

J. Org. Chem. 77(20) , 9227-35, (2012)

The p-methoxybenzyl protecting group (PMB) on various alcohols and an acid was efficiently and selectively cleaved by the action of a catalytic amount of silver(I) hexafluoroantimonate combined with 0.5 equiv of 1,3,5-trimethoxybenzene in dichloromethane at 4...

Electrophilic oxidant produced in the photodeoxygenation of 1,2-benzodiphenylene sulfoxide.

J. Org. Chem. 66(13) , 4576-9, (2001)

We report that the photodeoxygenation of 1,2-benzodiphenylene sulfoxide, 1, generates an intermediate capable of oxidizing the solvent benzene to phenol. The reactivity of the intermediate was probed with various substrates (2-methylbutane, chloride ion, and ...
