Atmospheric pressure chemical ionization (APCI) in air or in nitrogen with just traces of oxygen is shown to yield regioselective oxidation, dehydrogenation, and fragmentation of alkanes. Ozone is produced from ambient oxygen in situ and is responsible for the observed ion chemistry, which includes partial oxidation to ketones and C−C cleavage to give aldehydes. The mechanism of oxidation is explored...
Funktionalisierung von Alkanen: Wachse, die sich auf elektrisch geladenen Oberflächen befinden, gehen eine C‐C‐Bindungsfunktionalisierung mit Stickstoff ein und bilden Imine. Die Produkte werden online mittels Massenspektrometrie charakterisiert oder gesammelt und offline mit Raman‐Spektroskopie untersucht (siehe Bild).
