Trimethyl-isopropylbenzene

Figure 2 Absolute errors (kcal/mol) of different methods in the calculation of the barrier to isopropyl rotation in 2,4,6-trimethyl-isopropylbenzene.

As Margerison and Nyss noted 289) this reaction path is similar to one given by Benkeser et al.290) to explain the formation of l,l,3-trimethyl-3-phenylindane in the course of the metallation of isopropylbenzene by w-pentylsodium ...
