&Methyl-, @-ethyl-, and @-isopropylstyrene react with toluene at 110" in the presence of dispersed potassiuni to form the corresponding 1,3-diphenyl-2-alkylpropsnes in 60-9545 yields. Anethol reacts similarly to form 1-p-methoxyphenyl-2-meth- yl-3-phenylpropane in 68% yield. P,&Dimethylstyrene, however, fails to react with toluene. @-Ethylstyrene undergoes also ring closure with the formation of 1-methylindenr. ... It was reported recently that ...
