5,5'-Di-tert-butyl-2,2'-dihydroxy-3,3'-methanediyldibenzaldehyde and its allyl-protected dialcohol and dialdehyde precursors

S. Goetz, J. Barreira Fontecha and V. McKee

Abstract: 5,5'-Di-tert-butyl-2,2'-dihydroxy-3,3'-methanediyldibenzaldehyde, C₂₃H₂₈O₄, (IV), has been structurally characterized in two polymorphic forms. The tetragonal form, (in I4₁/a) has been reported previously but is redetermined and reinterpreted here, while the monoclinic form, (in C2/c) is reported for the first time. In both polymorphs, the molecule lies on a crystallographic twofold axis. Two precursors in the synthesis of (IV), namely 2,2'-bis(allyloxy)-5,5'-di-tert-butyl-3,3'-methanediyldibenzenemethanol (C₂₉H₄₀O₄) and 2,2'-bis(allyloxy)-5,5'-di-tert-butyl-3,3'-methanediyldibenzaldehyde (C₂₉H₃₆O₄) have also been characterized.

Formula: C₂₉H₄₀O₄, C₂₉H₃₆O₄ and C₂₃H₂₈O₄
