Abstract

Reaction of [(coe)2IrCl]2 (coe = cyclooctene) with AgPF6, arene (toluene, p-xylene, mesitylene), and diphenylacetylene, followed by counter anion exchange to BARF-, gives cyclobutadiene iridium complexes [(C4Ph4)Ir(arene)]BARF in 10-22% yield. Replacement of toluene in [(C4Ph4)Ir(toluene)]BARF by various ligands (trimethyl-phosphite, 1,3,5-triaza-7-phosphaadamantane, tert-butyl isonitrile) provides access to the half-sandwich cyclobuta-diene iridium complexes [(C4Ph4)Ir(L)3]BARF. Complex [(C4Ph4)Ir(toluene)]BARF in combination with [NBnEt3]Cl catalyses the insertion reaction between phenyl diazoacetate and various amines.
