Preparation and properties of the halogenoalkyl compounds [(η5-C5H5)(CO)2(PPh iMe3-i)Mo{(CH2)nX}] (n=3, 4; I=0-3; X=Br, I) and [{η5-C5(CH3)5}(CO) 3Mo{(CH2)nX}] (n=3, 4; X=Br, I)

The compounds [Cp(CO)2(PPhiMe3-i)Mo{(CH2) nBr}] (Cp=η5-C5H5, n=3, 4; i=0-3) and [Cp*(CO)3Mo{(CH2)nBr}] (Cp=η5-C5(CH3)5, n=3, 4) were prepared in medium to high yield by the reaction of the corresponding anion ([Cp(CO)2(PPhiMe3-i)Mo]- or [Cp*(CO)3Mo]-) with Br(CH2)nBr. The bromoalkyl compounds were subsequently reacted with NaI to give the corresponding iodoalkyl compounds [Cp(CO)2(PPhiMe3-i)Mo{(CH2) nI}] (n=3, 4; i=0-3) and [Cp*(CO)3Mo{(CH2)nI}] (n=3, 4). The iodoalkyl compounds can also be prepared by the reaction of the corresponding anion and α,ω-diiodoalkane in much lower yields. These compounds have been fully characterised and their properties are discussed. The crystal and molecular structure of [Cp(CO)2(PPh3)Mo{(CH2)3I}] is reported. The compound forms crystals in the monoclinic space group P21/n, with a Mo-C bond length of 2.40 A? and a C-I bond length of 2.13 A?. The compounds [Cp(CO)3W{(CH2)nX}] (X=Br, I; n=3-6) were also prepared in high yield and the crystal structures of [Cp(CO)3W{(CH2)5I}] and [Cp(CO)3W{(CH2)3Br}] are reported. The former compound forms orthorhombic crystals in the space group P21nb and the latter forms triclinic crystals in the space group P1?. Both have W-C bond lengths of 2.35 A?. The C-I bond length is 2.12 A?; the C-Br bond length is 1.94 A?.

Protonation of Metal-Metal Bonds in Cp2Ru2(CO)3(PR3) and Cp2Mo2(CO)4(PR3)2

Despite the much higher basicity expected for the Ru bearing the PR3 ligand in Cp(PR3)Ru(μ-CO)2Ru(CO)Cp, NMR studies demonstrate that protonation of this complex with CF3SO3H occurs at the Ru-Ru bond,
