実験手順

Similarly, 4,6-di-t-butyl-2-(α-methyl-4-methoxybenzyl) phenol was prepared from 2,4-di-t-butylphenol and α-methyl-4-methoxybenzyl alcohol. A yellow oil (b.p. 180° at 1.0 mm Hg) which crystallized was obtained. The product was recrystallized from methanol to give colorless needles melting at room temperature (Found: C, 81.0; H, 9.45 Calc. for C23H32O2 : C, 81.1; H, 9.47%). The pmr spectrum determined as above exhibited the following: δ1.35, 9H, S; δ1.37, 9H, S; δ1.63, 3H, D (J=7 Hz); δ3.78, 3H, S; δ4.17, Q, 1H (J=7 Hz); δ4.62, 1H, S; δ6.84, 2H, D (J=8 Hz); δ7.10-7.30, 4H, M.
