Abstract:
CF(3)OH is an atmospheric sink for hydrofluorocarbons (HFCs) and hydrofluoroethers (HFEs). Several new mechanisms, including catalyzation via H(2)O and OH radical, for the decomposition of CF(3)OH into HF and CF(2)O are studied using ab inito methods. The present work demonstrates that the OH radical has a strong catalytic effect on the transition state for the decomposition of CF(3)OH. The barrier is found to be reduced from 45.9 kcal mol(-1) for the unimolecular decomposition to 11.0 kcal mol(-1) for decomposition including H(2)O and OH.

Acid Halides to Carboxylic Acids: Hydrolysis
As shown below, the mechanism involves a nucleophilic attack by water at the carbonyl carbon to form a tetrahedral intermediate. This is followed by the reformation of the carbon–oxygen π bond along with the departure of a halide ion. A final proton transfer step yields carboxylic acid...
