Abstract

Ein ungeladener Gast: Wenn die TiO2-vermittelte photokatalytische Oxidation von Alkoholen zu Aldehyden oder Ketonen in organischen Lösungsmitteln wie Benzotrifluorid (BTF) ausgeführt wird, dominiert ein Sauerstoff-Transfer vom Disauerstoff zum α-Kohlenstoffatom des Alkohols den Reaktionsprozess.
