Tin oxide surfaces. Part 7.—An infrared study of the chemisorption and oxidation of organic Lewis base molecules on tin(IV) oxide

Abstract

Infrared spectroscopy has been used to show that hexachloroacetone is oxidised during chemisorption by tin(IV) oxide to produce a surface trichloroacetate, whereas the nitriles RCN[R = CCl₃, CH₃, C(CH₃)₃] are converted to surface acetimidato anions, RCONH^–, on adsorption. The acetimidato anions may be converted to the corresponding carboxylates by heating in vacuo, or hydrolysed by water vapour at 320 K to the corresponding amides.
