摘要：

We report new evidence relevant to the mechanism of ketene hydration. Specifically di-tert-butylketene (1) undergoes hydration to the acid 2 in 50% water-acetonitrile with general acid catalysis and a solvent isotope effect kH+/kD+ of 2.8. These facts indicate that the reaction occurs by rate-limiting proton transfer. © 1979, American Chemical Society. All rights reserved.
