Glass Surfaces

The application of x-ray photoelectron spectroscopy (ESCA) to the study of fiberglass surfaces is reported. Qualitatively, ESCA has been used to show the change in concentration of elements at the surface when fiberglass is subjected to heat and/or acid treatment. Diffusion of calcium to the surface as a function of temperature has been studied. Similarly, leaching of aluminum by acid as a function of pH is reported. The ability of ESCA to detect organic functional groups attached to fiberglass surfaces has been demonstrated for nitrogen and sulfur. Fiberglass coated with organic groups having chelating properties has been shown to extract metals from solution. It has also been demonstrated that ESCA can follow reactions of organic functional groups on glass surfaces, namely sulfonation of an amine.

Coupling reagents toward direct arylation of C2-H bonds in aryl azoles are often limited to aryl halides. Herein we report a functionalization of the acidic sp2 C-H bonds in benzothiazoles with benzaldehyde derivatives. Reactions proceeded in the presence of commercially ready CuFe2O4 catalyst. Scope of functional groups included chloro, nitro, cyano, and ester groups.
