| Abstract: | In the presence of catalytic amounts of samarium trichloride, acetophenone diethyl ketals reacted with acetyl chloride to give 1,3,5 - triarylbenzenes 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. |
