B. Akermark et al., CONFORMATIONS OF (ETA(3)-CYCLOHEXENYL)PALLADIUM SYSTEMS - A MOLECULARMECHANICS (MM2) STUDY, Organometallics, 14(4), 1995, pp. 1688-1693
The primary products from palladium(II)-assisted nucleophilic addition
to 1,4-cyclohexadienes ((eta(3)-cyclohexenyl)palladium complexes) hav
e been investigated by molecular mechanics (MM2). The observed couplin
g constants can best be explained by a rapid equilibrium between chair
- and boatlike conformations. Methods to estimate the relative amounts
of the boat and chair conformations of the complexes are presented.
