Abstract

The syntheses of the monomeric cationic complexes [Cp ^*(CO) Ir(R)(CH ₂Cl ₂)] were attempted (Cp ^*) η5-C ₅Me ₅, R) Me, H). The target complexes were not obtained; instead, dimeric products were isolated in high yields. The reaction between Cp ^*(CO)Ir(Me)Cl and [Li(Et ₂O) _2.5][BAr ^F ₄] afforded the cationic complex [{Cp ^*(CO)Ir(Me)} ₂(μ-Cl)][BAr ^F ₄](4) in high yield. Complex 4 has been characterized by ¹H NMR, ¹³C{ ¹H} NMR, and IR spectroscopies. Reaction of Cp ^*(CO)Ir(H) ₂ with [CPh ₃][BAr ^F ₄] produced the dicationic complex [Cp ^*(CO)Ir(μ-H)] ₂[BAr ^F ₄] ₂ (9) in excellent yield. Complex 9 has been characterized by ¹H NMR and IR spectroscopies as well as elemental analysis and single-crystal X-ray diffraction. An X-ray structural determination was also carried out on the related complex [Cp ^*(Cl)Ir(μ-H) ] ₂ (14). The solid-state structures of 9 and 14 are compared briefly.
