Procedure

Under the reaction conditions described in Example 1, 64 ml KOH and 19.2 ml PPh3 were added over 43 min. After five more minutes, the reactor was cooled and vented. A 92% yield of potassium phenylacetate and 4% methyl phenylacetate was obtained on a nearly quantitative conversion. 98% of the stiochiometric amount of KOH was added.
