Explanation
Another way of rationalising is through the use of the Hard-Soft Acid-Base principle. The dichlorocarbene generated is a soft electrophilic species while the oxyanion form of the phenoxide is a hard nucleophilic species. The nucleophilic pi bond is much softer and thus, it is much more favourable for it to be the attacking nucleophile (soft-soft interaction) rather than the negatively-charged oxygen atom (hard-soft interaction).

In general, an associative mechanism occurs when the entropy of the transition state is lower than the reactants and thus the transition state is more ordered.
