実験手順

134 g (0.5 mol) of molten dimeric 4-isopropenylphenol and 120 g (1.07 mol) of diisobutylene are simultaneously added dropwise over a period of 4 hours at around 90° C to a suspension of 20 g of an acid-activated fuller's earth in 100 ml of toluene. The mixture is then left to react for another 2 hours at 90° C, after which the catalyst is filtered off and the solvent distilled off. Fractional distillation of the residue gives a fraction which distills over at 160°-170° C./12 Torr and subsequently solidifies in crystalline form. Recrystallisation from petroleum ether gives 41.2 g (34 % of the theoretical) of 5-hydroxy-1,1,3-trimethyl-3-neopentyl indane (IV) melting at 102° C. ##STR22##
