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...
Based on a study of competitive substituent effects in a Claisen–Schmidt reaction, interfacial effects have been shown to play an important role in accelerated reactions that occur in thin films and droplets. A role for the interface in an accelerated C−C bond‐formation reaction between 6hydroxy‐1‐indanone and aromatic aldehydes is indicated by cooperative interactions between p‐methylbenzaldehyde...
