Indium(III) chloride is an effective Lewis acid catalyst for one-pot allylation-etherification and reductive etherification of aromatic aldehydes with functional silanes, allyltriethoxysilane, and triethoxysilane, at room temperature to afford corresponding ethers in excellent yields. Additionally, the InCl3-catalyzed reactions in the presence of TMSCl offer significant advantages in its ease of working-up for the preparation of unsymmetrical ethers under mild conditions.

The electrochemical cyclization of a series of ortho-halo-substituted homoallyl ethers and esters to functionalized indanes catalyzed by Ni(II) catalyst precursors derived from Ni(cyclam)Br2, (cyclam = 1,4,8,11-tetraazacyclotetradecane) and Ni(tmc)Br2, (tmc = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane) is reported. The starting homoallyl ethers were synthesized using either a one-pot method for allylation of aldehydes or by direct allylation of the corresponding acetals using bismuth triflate as a catalyst. The remarkably low toxicity, low cost and ease of handling of bismuth salts coupled with the mild nature of the electrochemical procedure makes this approach to indane synthesis especially environmentally friendly and attractive.
