1.2- dichloro trans

It is believed that equatorial substituents such as chlorine or bromine would increase the guest diameter beyond the allowed values (assuming that the guest molecules stack roughly parallel to the canal68)). Support for this comes from the study of fluorocyclohexane where the population of the axial conformer is not enhanced to any major extent70. Nitro-71) and cyano-cyclohexane, trans-l,2-dichloro-, trans-1,2-dibromo-, tram-1,4-dichloro-, trans-1,4-dibromo-, and trans-l-bromo-4-chloro-cyclohexane all pack most efficiently in the thiourea canals as the axial or diaxial conformer 68,72. Tram-2,3-dichloro-1,4-dioxane behaves similarly73. In contrast isocyanato-, tram-1,4-diiodo-, trans-1 -bromo-4-iodo-, and tram-1 -chloro-4-iodo-cyclohexane are present as mixtures of the axial/equatorial or diaxial/diequatorial conformations as appropriate 68,72). The reason for this anomalous behaviour of the iodosubstituted cyclohexanes is not clear. [Pg.164]

An ion of nominal m/z 442 was produced from cis-dichloro-trans-dihydroxo-bis-2-propanamine/platinum (IV) (CHIP) by ion/molecule reactions (IMR) of the major electron impact (El) fragment ion with the neutral molecule. As shown in Figure 3, this ion dissociated when irradiated by the cw laser for ca. 500 ms to produce two daughter photofragment ions, m/z 366 and m/z 311, by loss of various ligands (Equation 1).
