摘要：

Deprotonation of Ir4(CO)11PPh2H (1) in the presence of [AuPPh3][PF6] yields the novel species Ir4(CO)11(PPh2AuPPh3) (2), which possesses a tetrahedral framework bearing a terminally bound PPh2AuPPh3 ligand. When heated in toluene, 2 is converted into the phosphido species Ir4(CO)10(μ-PPh2)(μ-AuPPh3). © 1990.
