Abstract

Indium(III) tris(cyclopentadienide) In(C₅H₅)₃ reacts with diphenylphosphine at room temperature to form the indium(I) derivative In(C₅H₅), P₂Ph₄, and C₅H₆. These products are consistent with the occurrence of an initial cyclopentadiene elimination reaction between In(C₅H₅)₃ and HPPh₂ and then reduction at indium. In contrast, tert-butyl alcohol undergoes a typical stoichiometric cyclopentadiene elimination reaction with In(C₅H₅)₃ to form [(C₅H₅)₂-InO(t-Bu)]₂. Acetylacetone (Hacac) also reacts with In(C₅H₅)₃, but the expected product(s) of the cyclopentadiene elimination reactions (C₅H₅)₂In(acac) and (C₅H₅)In(acac)₂ are unstable and redistribute their ligands to form In(C₅H₅)₃ and In(acac)₃, as appropriate. The reagent tert-butylamine does not eliminate cyclopentadiene when combined with In(C₅H₅)₃ at room temperature.
