A heterogeneous C-O coupling reaction between aryl iodides and aliphatic alcohols was achieved in neat alcohol or toluene at 110 °C in the presence of 10 mol% of the MCM-41-immobilized 1,10-phenanthroline-copper(i) complex [MCM-41-1,10-phen-CuI] with Cs2CO3 as a base, yielding a variety of aryl alkyl ethers in good to excellent yields. The new heterogeneous copper catalyst can easily be prepared by a simple procedure from commercially available and inexpensive reagents, and recovered by filtration of the reaction solution and recycled at least 8 times without significant loss of activity.

Merrifield-bound o-cresol undergoes electrophilic aromatic chlorination using SO2Cl2 leading to para/ortho ratios in excess of 50, the highest such ratio reported for this chlorinating agent. Model studies suggest that this significant para/ortho ratio results not just from steric effects but that considerable electronic influence can be detected.
