Thermolysis of 2-(N-acylamino)benzyl methyl ethers, in the presence of an acid catalyst and triphenylphosphine, or 2-(N-acylamino)benzylphosphonium salts is found to serve as a novel method for indole formation, in particular for the synthesis of 2-trifluoromethylindoles. The reaction of the benzyl methyl ethers is suggested to involve a phosphonium intermediate, which thermally decomposes to the indoles.

The title compounds 20, 21, and 22 have been prepared in modest yields by a two-step reaction involving first the reaction of bromoarenes 3, 7, and 8 with lithioalkyl- and lithioarylacetonitriles under aryne-forming conditions.The cyano products 10, 14, and 16 so formed were then converted to the corresponding isochroman-3-ones by acidic hydrolysis.
