The selective syntheses of 1- and 2-indan-one compounds from 2-ethynylbenzyl ethers have been achieved with suitable catalysts and solvents. The highly acidic [tris(pentafluorophenyl)phos-phine]gold hexafluoroantimonate [(C6F5)3AuSbF6] in nitromethane (MeNO2) preferably gives 1-indan-ones whereas [(ortho-biphenyl) di(tert-butyl)phosphine] gold triflimide [(tBu)2(o-biphenyl) AuNTf2] in dichloroethane tends to form 2-indanone derivatives. For 2-indanone products, we isolated two indenyl methyl ethers for deuterium labeling analyses, providing evidence for p-alkyne activation.

(Chemical Equation Presented) The first example of isolation and X-ray crystallographic structural characterization of two conformers arising from rotation along a diacetylenic bond is reported. In both the conformers extensive π-π interactions are observ
