tBu2P–P(SiMe3)Li reacted with [(η6-C6H6)RuCl2]2at–40 °C in the presence of PR3(PR3=PEt3,PEt2Ph, PEtPh2) by the nucleophilic addition of the tBu2P–P(SiMe3) moiety to the benzene ring to yield solely the complexes [(R3P)2Ru(Cl)-{η5-C6H6(Me3SiP–PtBu2)}] (1). These products decomposed slowly at ambient temperature to yield benzene, Ru clusters, and small amounts of the dinuclear ruthenium complexes [{(R3P)2Ru}2(μ,η2:2-P2)2Ru(PR3)2](Ru–Ru)(6). Single-crystal X-ray diffraction studies of [(PhEt2P)2Ru(Cl){η5-C6H6(Me3SiP–PtBu2)}] (1b) and [(Ph2EtP)2Ru(Cl){η5-C6H6(Me3SiP–PtBu2)}] (1c) revealed that the addition of the tBu2P–P(SiMe3) group occurred through an exo pathway. Complex 6a (R = Et) displays a planar rectangu- lar P4 system consisting of t wo P2 units and a Ru–Ru distance that lies in the range of a single bond.
