  A Highly Reactive Ruthenium Phosphido Complex Exhibiting Ru−P π-Bonding

  摘要：

  Multiple bonding in the terminal phosphido complex [Ru(PCy2)(eta(5)-indenyl)(PPh3)] (2a) is clearly demonstrated by solution, solid-state, and computational studies. Reactions of this dark blue, half-sandwich complex with CO, MeI, HNEt3Cl, HCl, NH4PF6, H-2, and Et3SiH demonstrate an unusual range of behavior resulting from combined coordinative unsaturation at Ru, high nucleophilicity/basicity of the phosphido P, and pi-character of the Ru-P interaction. The terminal, pi-bound phosphido structure is general for a range of PR2 species (R = Pr-i (2b), Ph (2c), Tol(p) (2d)). The very reactive diarylphosphido analogues 2c,d have been observed spectroscopically at low temperatures and can be trapped quantitatively as their CO adducts, [Ru(PAr2)(eta(5)-indenyl)(CO)(PPh3)] (3c,d), in which the Ru-P bond order is reduced to 1. Complex 2a and its analogue [Ru(PPr2i)(eta(5)-indenyl)(PPh3)] (2b) are consistently isolated with similar to 15% of their structural isomers, the ruthenium hydrido phosphaalkenes 9a, b, resulting from an apparent 1,2-H shift.
