Abstract: Synthesis of (E)-2-hydroxy-5-(aryldiazenyl)benzaldehydes was investigated. Various Lewis acids were tested as catalyst to achieve regioselectivity. In addition to various commercial catalysts, mesoporous Zn/SBA-15 was synthesized through a modified direct method with chloride salt as zinc… read more here.
