| Abstract: | The dynamic behaviour of [Pt(/gh3-allyl){P(cyclohexyl)3}2]+[PF6]- has been reinvestigated, and the earlier interpretation of restricted rotation about the Pt—P endorsed. The activation parameters were obtained. [Pt(/gh3-allyl)(PPri3)2]+[PF6]- behaves similarly, while it has not prove possible to stop the rotation in [Pt(/gh3-allyl){P(CH2Ph)3}2]+[PF6]-. |
