摘要：

The displacement of Et3SiH and THF from the (eta(6)-C6H6)Cr(CO)(2)(HSiEt3) and (eta(6)-C6H6)Cr(CO)(2)(THF) complexes has been studied. Both solvents are displaced from the metal center by a dissociative mechanism. Kinetic and thermodynamic measurements suggest that the Cr-HSiEt3 bond is similar to 3 kcal/mol more stable than the Cr-THF interaction.
