Cationic Gold Catalyst Poisoning and Reactivation
High gold affinity impurities (halides, bases) in solvents, starting materials, filtration, or drying agents could affect the reactivity of gold catalyst adversely, which may significantly reduce the TON of cationic gold-catalyzed reactions. Use of a suitable acid activator (e.g., HOTf, In(OTf)3) reactivates the gold catalyst and makes the reaction proceed smoothly at low gold catalyst loading.
متن کاملThe Gas Phase Oxidation of Acetaldehyde Reaction Mechanism and Kinetics
The mechanism of the low temperature oxidation of gaseous acetaldehyde was investigated in the temperature range of 1 50-400?°C. The minor, intermediate and major products were identified and measured quantitatively by sampling directly into the ionization chamber of an MS10-C2 mass spectrometer from the reactor. The formation of H2O, CO, CO2, HCOOH, H2, HCHO, CH3COOH and CH3OH as the major pro...

The Reaction of Halogenacetic Acids with Glutathione and Cysteine. the Mechanism of Iodoacetate Poisoning
SINCE Lundsgaard [1930] drew attention to the remarkably toxic nature of certain of the halogenacetic acids and their role as powerful and selective inhibitors of lactic acid formation and of alcoholic fermentation, these compounds have assumed great importance in physiology, and the numerous investigations of fundamental value to the theories of muscular contraction, tissue glycolysis and ferm...
متن کاملSocial information guides infants' selection of foods.
Two experiments investigated the influence of socially conveyed emotions and speech on infants' preferences in the food domain. After watching films in which two unfamiliar actresses each spoke while eating a different kind of food, 12-month-old infants were allowed to choose between the two foods. In Experiment 1, infants selected a food endorsed by a speaker of their native language who displ...
