摘要
This paper presents a force field to evaluate the arene-Cr(CO)(3) interactions in the (eta(6)-arene)-Cr(CO)(3) polysubstituted complexes. On the basis of several molecules for which X-ray data are available, a comparative study of several force fields has been undertaken. Similarly the comparison has been established with results obtained by PM3(tm) semi-empirical method. The bases and the possibility to perform the transferability of this force field ape also presented. Moreover, influence of the most stable conformation of five other (eta(6)-arene)-Cr(CO)(3) on their corresponding reactivity is studied. (C) 1999 Elsevier Science B.V. All rights reserved.
