Unexpected photostability improvement of aromatics in polyfluorinated solvents.
The photostability of aromatic compounds in the presence of air is significantly improved through perfluoroalkylation of the corresponding aromatic cores and use of polyfluorinated solvents despite higher O(2) concentration in polyfluorinated solvents than in hydrocarbon solvents.
متن کاملThe doping effect of fluorinated aromatic hydrocarbon solvents on the performance of common olefin metathesis catalysts: application in the preparation of biologically active compounds.
Aromatic fluorinated hydrocarbons, used as solvents for olefin metathesis reactions, catalysed by standard commercially available Ru precatalysts, allow substantially higher yields to be obtained, especially of challenging substrates, including natural and biologically active compounds.
متن کاملKidney cancer and hydrocarbon exposures among petroleum refinery workers.
To evaluate the hypothesis of increased kidney cancer risk after exposure to hydrocarbons, especially those present in gasoline, we conducted a case-control study in a cohort of approximately 100,000 male refinery workers from five petroleum companies. A review of 18,323 death certificates identified 102 kidney cancer cases, to each of whom four controls were matched by refinery location and de...
متن کاملOccupational exposure to organic solvents and K-ras mutations in exocrine pancreatic cancer.
Occupational exposure to hydrocarbon solvents has been found to be associated with an increased risk of exocrine pancreatic cancer (EPC), the human tumor with the highest prevalence of K-ras mutations. Ras genes are critical DNA targets for chemical carcinogens. We analysed the relationship between past occupational exposure to hydrocarbon solvents and mutations in codon 12 of the K-ras gene in...
متن کامل2 Ft - Ir and Ft - Raman Spectra , Vibrational Assignments , Ab Initio and Dft Analysis of , - Dichlorotoluene
Toluene, also known as methylbenzene or phenylmethane, is a clear, waterinsoluble liquid with the typical smell of paint thinners, redolent of the sweet smell of the related compound benzene. It is an aromatic hydrocarbon that is widely used as an industrial feedstock and as a solvent. Like other solvents, toluene is also used as an inhalant drug for its intoxicating properties [1,2]. Toluene r...
