Only a few studies investigating the pressure effect on the formation of host-guest complexes have been carried out hitherto. A large effect of pressure has been observed for reactions in which atoms or molecules are compressed into the cavity of a container molecule without releasing other molecules out of the cavity. The volume of such a reaction is highly negative so that high pressure favors complex formation. One example is the incorporation of noble gas atoms into the cavity of buckminster fullerene Cgo which proceeds at 250 MPa and 600 °C [10]. 

The inclusion of buckminster fullerene Ceo into the cavity of a p-benzylcalix[5]-arene in toluene solution reported by Isaacs et al. [16], is associated with a dramatic partial molar volume change of AV = +195 cm mol which is consistent with the displacement of two toluene molecules from the cavity of the calixarene during complex formation (Fig. 11.5). 

The reaction of the dimers (Fp>2, Fp 2 with isocyanides in the presence of a catalytic quantity of triethylborane to give a mono substituted product is proposed to go via a radical chain process.The photoelectron spectra of the n -acetylides CpFe(CO>2C=CR R = H, Bu and Ph have been analysed and show significant interaction of the ir-orbitals with the metal dx orbitals based on the splitting of metal-based ionization bands, shifts in Cp-based and acetylide based ionizations, changes in ionization cross sections (Hel/Hell) and the vibrational fine structure in the metal based ionizations. The 19e complex [CpFtffCsMee) has been used as an electron reservoir in the multiple electron reduction of Buckminster fullerene. ...
