In acidic solution, the weak nucleophile water attacks carbonyl carbon atom, having protonated oxygen atom; then carboxylic acid derivatives and alcohol groups are formed [28]. Determination of acid dissociation constants ([pK.sub.a]) of bicyclic thiohydantoin-pyrrolidine compounds in 20% ethanol-wat...
