## Abstract Infrared analysis has shown that acid‐catalyzed hydration of ethylthioethyne in heavy water does not involve the uptake of deuterium in the initial compound. This confirms earlier evidence that protonation of the triple bond is the rate‐determining step. Values for the entropy of activ

## Abstract Additional evidence for the occurrence of a rate determining proton transfer in the hydration of 1‐alkynyl ethers is afforded by the value of the solvent deuterium isotope effect, k/k = 1.7. The addition of water to 1‐ethoxy‐1‐propyne was investigated in a series of alcohol‐water mixtu
