A recent literature report that 1-dodecene reacts with phenol in the presence of sulfated zirconium oxide (superacid), or 1-dodecanol with phenol in the precsence of H-Mordenite (zeolite), to afford mostly para-substituted alkylphenols has been shown to be incorrect. The product with zirconium is a mixture of ortho/para isomers (≈ 50–65/50–35), and not the exclusive para isomer as reported. The major product in the case of zeolite catalysis is the ...
