Hagemann’s esters can be converted into highly functionalized phenols or arenes. The systematic functionalization of Hagemann’s ester derivatives permits the preparation of triand tetraalkylsubstituted phenols or tetra-, penta-, and hexaalkyl-substituted benzenes. Kotnis’s aromatization procedure was found to be solvent dependent, and Suzuki couplings were found to be sensitive to steric hindrance
