For details of preparation, see Ref. Alumina catalyst prepared by methods other than the above gave poor results
- NMR of 2-phenylindene, [sgrave] 3.7(s,2H),6.9–7.5(m, 10H) and 3-phenylindene [sgrave] 3.2(d,2H), 6.15(t,1H), 6.8–7.3(m,9H); NMR of a 1:1 mixture of 2- and 3-phenylindene gives the following signals: ò 3.35(d,2H), 3.6(s,3H), 6.3(t,1H) 6.8–7.8 (m,9H), the shift in value is probably due to association
