Fluorination of single-wall carbon nanotubes
Ž . Purified single-wall carbon nanotubes SWNTs were fluorinated at several different temperatures. Product stoichiometries were determined and electron microscopy was used to verify whether or not the fluorination was destructive of the tubes. SWNTs fluorinated at three different temperatures were then defluorinated using hydrazine. Raman spectroscopy and resistance measurements were utilized ...
متن کاملSilver-catalyzed amidation of benzoylformic acids with tertiary amines via selective carbon-nitrogen bond cleavage.
A novel approach towards the synthesis of α-ketoamides using tertiary amines as nitrogen group sources via C-N bond cleavage has been developed. In the presence of Ag2CO3 and K2S2O8, α-keto acids reacted with tertiary amines to afford the corresponding α-ketoamides in good yields.
متن کاملCarbon-carbon bond cleavage in activation of the prodrug nabumetone.
Carbon-carbon bond cleavage reactions are catalyzed by, among others, lanosterol 14-demethylase (CYP51), cholesterol side-chain cleavage enzyme (CYP11), sterol 17β-lyase (CYP17), and aromatase (CYP19). Because of the high substrate specificities of these enzymes and the complex nature of their substrates, these reactions have been difficult to characterize. A CYP1A2-catalyzed carbon-carbon bond...

متن کاملEffect of the fluorination technique on the surface-fluorination patterning of double-walled carbon nanotubes
Double-walled carbon nanotubes (DWCNTs) are fluorinated using (1) fluorine F2 at 200 °C, (2) gaseous BrF3 at room temperature, and (3) CF4 radio-frequency plasma functionalization. These have been comparatively studied using transmission electron microscopy and infrared, Raman, X-ray photoelectron, and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy. A formation of covalent C-F ...
