Two related compounds containing p-tert-butyl-o-methylene-linked phenol or phenol-derived subunits are described, namely 5,5'-di-tert-butyl-2,2'-dihydroxy-3,3'-methylenedibenzaldehyde, C(23)H(28)O(4), (I), and 6,6'-di-tert-butyl-8,8'-methylenebis(spiro[4H-1,3-benzodioxin-2,1'-cyclohexane]), C(35)H(48)O(4), (II). Both compounds adopt a 'butterfly' shape, with the two phenol or phenol-derived O atoms in distal positions. Phenol and aldehyde groups in (I) are involved in intramolecular hydrogen bonds and the two dioxin rings in (II) are in distorted half-chair conformations.
描述了两种含有对叔丁基-邻亚甲基连接的苯酚或苯酚衍生亚基的相关化合物，即5,5'-二叔丁基-2,2'-二羟基-3,3'-亚甲基二苯甲醛，C(23)H(28)O(4)，(I)，以及6,6'-二叔丁基-8,8'-亚甲基双(螺[4H-1,3-苯并二恶英-2,1'-环己烷])，C(35)H(48)O(4)，(II)。两种化合物均呈“蝴蝶”形状，两个苯酚或苯酚衍生的O原子位于远端位置。(I)中的苯酚和醛基参与分子内氢键，(II)中的两个二恶英环呈扭曲的半椅式构象。
