Abstract
The Compounds [(PMe3)2RhCl]2 and [Rh(PMe3)4]Cl react with indenyllithium to give C9H7Rh(PMe3)2. The strong Lewis basicity of this complex is demonstrated by its reactions with NH4PF6, MeI and MeCOCl which lead to the cations [C9H7RhR(PMe3)2]+ (R = H, Me, COMe). The hydrido complex [C9H7RhH(PMe3)2]PF6 reacts with 1,5-C8H12, CO and PMe3 by complete displacement of indene to give [Rh(PMe3)2(C8H12)]PF6, [Rh(PMe3)2(CO)3]PF6 and [Rh(PMe3)4]PF6. Reaction of [C9H7RhH(PMe3)2]PF6 with C2H4 yields an equilibrium mixture containing the cationic tris(ethylene) complex [Rh(PMe3)2(C2H4)3]+ .
