In the presence of catalytic amounts of samarium trichloride, acetophenone diethyl ketals reacted with acetyl chloride to give 1, 3, 5-triarylenzenes in high yields. This reaction proceeds smoothly in a variety of solvents with various lanthanide trichlorides, providing a novel method for the synthesis of 1, 3, 5-triarylbenzene. A reasonable mechanism for this reaction is suggested.
