General description

InCl3 is an efficient water-stable Lewis acid catalyst used in many organic transformations. It is moderately toxic and shows high tolerance to most of the oxygen and nitrogen containing functional groups. Owing to its optoelectronic properties it is also used to prepare many semiconductor materials.

Application

Indium(lll) chloride can be used as a catalyst to synthesize:
  • Indolylindolines through self-addition of indoles.
  • Vinyl indoles from unfunctionalized indoles and vinyl azides.
  • Variety of cycloadducts through the reaction of olefinic acetals with isoprene and cyclopentadiene.
  • N-tosylimines through a condensation reaction of aldehydes with p-toluenesulfonamide.
