Abstract
Indium metal and selected indium(III) compounds have emerged as an alternative tool in organic synthesis, but the use of compounds with the metal at the oxidation state (I) has been hardly explored. This account discusses the major routes to indium(I) compounds, their chemical properties and applications in organic synthesis.
Keywords: indium(I), indium monohalides, oxidative insertion reactions, hydrochalcogenation, epoxide ring opening, carboncarbon bond formation
