  Steric limitations in associative substitution reactions of Os3(CO)9(μ-C4Ph4)

  摘要：

  Reactions of the cluster Os-3(CO)(9)(mu-C4Ph4) (I) with a large number of smaller P-donor nucleophiles (Tolman cone angle theta less than or equal to 143 degrees) proceed rapidly in heptane at room temperature via associative adduct formation to form the monosubstituted products. However, reactions with several larger P-donor nucleophiles (theta greater than or equal to 145 degrees) in heptane at room temperature yield, in a single observable bimolecular step, a mixture of mononuclear and dinuclear products and it is therefore not possible to synthesize the monosubstituted clusters directly with these larger ligands. Crystallographic structures of Os-3(CO)(8)(etpb)(mu-C4Ph4).(CH3OH) (2etpb) (etpb = P(OCH2)(3)CEt) and Os-3(CO)(8)(P(OPh)3)(mu-C4Ph4).(C6H14) (2P(OPh)(3)) have been determined and show that the substituent has displaced a CO ligand from the Os(CO)(4) moiety in 1.
