Ghlorotris(triphenylphosphine) rhodium causes the decarbonylation of aroyl to aryl chlorides in excellent yields at relatively low temp. At higher temp., only catalytic amounts of the reagent are required. — E A mixture of henzoyl chloride, the above Rh-compound, and benzene heated 15 min. at 80° chlorobenzene. Y almost 100%. F. e. s.
