Copper-catalyzed silylation of cyclopropenes using (trifluoromethyl)trimethylsilane.
A variety of cyclopropenes undergo direct silylation using (trifluoromethyl)trimethylsilane in the presence of a copper-bisphosphine catalyst; under these conditions, cyclopropenes that might otherwise undergo ring-opening are silylated efficiently.
متن کاملRegioselective silylation of pyranosides using a boronic acid/Lewis base co-catalyst system.
The combination of a boronic acid and a Lewis base, both employed in substoichiometric amounts, enables the regioselective silylation of cis-diol groups in alkylpyranoside substrates. The proposed mode of activation involves the formation of a tetracoordinate adduct that displays enhanced nucleophilicity at the boron-bound alkoxide groups.
متن کاملReductive Remediation of Pollutants Using Metals
Metal systems have been extensively used for the abiotic remediation of recalcitrant pollutants. Zero-valent metals such as iron (Fe 0 ), zinc (Zn 0 ), magnesium (Mg 0 ) have been used for the reductive dechlorination of organic compounds Nanoscale zero-valent iron particles have been reported to be very effective for the transformation and detoxification of a wide variety of contaminants, such...
متن کاملSeparation of ursodeoxycholic acid by silylation crystallization
Background: Ursodeoxycholic acid is an important clinical drug in the treatment of liver disease. In our previous work, ursodeoxycholic acid was prepared by electroreduction of 7-ketolithocholic acid. The separation of ursodeoxycholic acid from the electroreduction product (47% (w/w) ursodeoxycholic acid) by silylation crystallization is described herein. Results: N,N-dimethylformamide was used...
متن کاملDetermination of Urinary PAH Metabolites Using DLLME Hyphenated to Injector Port Silylation and GC-MS-MS.
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants and well-known carcinogens. Hydroxy derivatives of PAH are considered as biomarkers of PAH exposure, and there is a need to measure these metabolites at low concentrations. So, a precise and eco-friendly analytical method has been developed for rapid determination of PAH metabolites. For the first time, a new analyt...
