This article describes our efforts in establishing a practical and sustainable synthesis of bis(2-hydroxy-3,5-di-t-butylphenyl)methanone. We found that the phenol-aldehyde condensation reaction can be efficiently catalyzed by sulfonic acid-functionalized microporous carbon spheres (MCS-SO3H). Additionally, we developed practical and sustainable procedures for the synthesis of the title ligand by using readily available reagents instead of toxic chromium trioxide and fuming boron tribromide.
Described is our effort toward establishing a practical and sustainable synthesis of bis(2-hydroxy-3,5-di-t-butylphenyl)methanone. In it, we found the phenol-aldehyde condensation could be efficiently catalyzed by sulfonic acid-functionalized microporous carbon spheres (MCS-SO3H). Additionally, we developed practical and sustainable procedures for the synthesis of the title ligand by applying readily available reagents in lieu of toxic chromium trioxide and fuming boron tribromide.
