In this work, we report an efficient and facile preparation of diphenylmethylethers (benzydryl ethers, DPM-ethers) from benzhydrol and alcohols or phenols. Wells-Dawson heteropolyacid (H6P2W 18O62.24H2O), bulk or supported on silica showed catalytic activity for DPM-ethers preparation in toluene, at...
