摘要

The radical initiated reactions of Ru₃(CO)₁₂ with pyrazolyl substituted diphosphazanes Ph₂PN(R)PPh(N₂C₃HMe₂-3,5) [R = (S)-*CHMePh (1) or CHMe₂ (2)] proceed via P–N(pyrazole) bond rupture resulting in the formation of phosphido clusters, [Ru₃(CO)₅(μ_sb-CO)₂(μ₃-N,N′-η¹:η¹:η¹-N₂C₃HMe₂-3,5){μ-P,P′-Ph₂PN(R)PPh}] [R = (S)-*CHMePh (3) or CHMe₂ (4)]. The pyrazolate moiety adopts an unusual triply bridging μ₃-η¹:η¹:η¹-mode of coordination in these clusters.
