Tunneling in proton transfer reactions in solution. Final report

OSTI ID:7259599
The rates of base-catalyzed ionization of several ketones have been measured. The results for 2,4-dimethyl-3-pentanone and 3,5-dimethyl-4-heptanone indicate that tunneling does not occur and the rate the determining step in detritiation is not the T/sup +/ transfer. In the reactions with acetylfurans, acetylthiophenes and acetylpyridines isotope effects vary in accordance with the current theory. Tunneling is significant only for the proton transfer from 2,4,6-trimethyl-3-acetylpyridine. In the iodination of acetone catalyzed by pyridine bases, k/sup H//k/sup D/ varies according to the current theory. Tunneling is significant only when sterically hindered pyridines are used. The rates of detritiation have been measured for several substituted acetophenones and isobutyrophenone.
