A molecular mechanics investigation of the structures and energetics of two classes of Ru(II) complexes with applications in homogeneous catalysis

摘要

We have used the extensible systematic forcefield (ESFF) to model two classes of chiral organometallic complexes with Ru(II) centres, both complexes having been shown to have excellent catalytic performance with respect to asymmetric ketone hydrogenation. Our results compare favourably with all available experimental data for these complexes, illustrating that the ESFF can be applied successfully to these systems. The results we obtain are useful and relevant in connection with the study of these complexes as catalysts and in turn the results support the further use of the ESFF for modelling other organometallic complexes.
