The complex [IndCpMo(NCMe) 2 ][BF 4 ] 2 provides a suitable entry to the synthesis of IndCpMoBr 2 and IndCpMoMe 2 . The latter, also available from IndCpMoX 2 (X=Cl, Br) and MeMgCl, reacts with HCl to give IndCpMoCl(Me) which, in turn reacts with NaSPh to yield IndCpMo(SPh)(Me). Cyclic voltammetry shows that these three alkyl complexes undergo a 1e reversible oxidation to 17 e Mo V cations. IndCpMoCl(Me) is oxidized by [Cp 2 Fe]BF 4 to afford [IndCpMoCl(Me)]BF 4 in 95% yield. Reaction of [IndCpMo(NCMe) 2 ][BF 4 ] 2 with KBPz 4 in CH 2 Cl 2 /NMF leads to [IndCpMo(κ 2 -BPz 4 )]BF 4 . Taken together with previous reports these results show that the indenyl ring slows down substitutional chemistry at the Cp2′Mo(IV) fragment (Cp′=Cp, Ind) by steric reasons, overshadowing any acceleration due to a possible indenyl effect.
