摘要

3. Part of the dimethyl-p-tolyl carbonium ion formed may lose a proton to form 1-methyl-$- ispropenylbenzene; the latter on reaction with the dimethyl-p-tolylcarbonium ion forms probably 2, 4-di-p-tolyl-4-methyl-2-pentylcarbonium ion. The latter through an internal addition to the benzene ring and a. subsequent loss of a proton yields 1, 3, 3, 6-tetramethyl- lp-tolylindan (I).
