Mixed-metal cluster chemistry: 32. Synthesis, structure, and reactivity of a trimetallic molybdenum-iridium carbonyl cluster possessing a μ 3 -η 2 -benzyne ligand

Abstract

The reaction of Mo2Ir2(μ-CO)3(CO) 7(η5-C5H5)2 and Ir(CCCH2OH)(CO)(PPh3)3 in refluxing toluene gives the molybdenum-iridium cluster MoIr2(μ3- η2-C6H4)(μ-PPh2)(μ-CO) 2(CO)4(η5-C5H5) (1) in low yield. Mo2Ir2(μ-CO)3(CO) 6(PPh3)(η5-C5H5) 2 (2) is a po
