      The reaction of Ph3SnOH with   Ir4(CO)12 in the presence of   [Bu4N]OH in methanol solvent gave two products,   [Bu4N][Ir4(CO)11(SnPh3)]   (1; 45% yield) and   [Bu4N][Ir4(CO)10(SnPh3)2(μ-H)]   (2; 5.5% yield), and the reaction of   Ir4(CO)11(PPh3) with   Ph3SnOH in the presence of [Bu4N]OH gave   the complex   Ir4(CO)10(SnPh3)(PPh3)(μ-H)   (3) in 44% yield. It is proposed that the   reactions occur by the addition of the anion   [OSnPh3] generated in situ to a CO ligand   of the Ir4(CO)12 to form a   stannyl-substituted metallocarboxylate ligand that subsequently   loses CO2 and transfers the SnPh3 group to   a metal atom.
