Abstract In this work, we have compared the host abilities of closely related compounds (+)-(2 R ,3 R )-1,1,4,4-tetraphenylbutane-1,2,3,4-tetraol ( TETROL ) and (2 R ,3 R )-(−)-2,3-dimethoxy-1,1,4,4-tetraphenylbutane-1,4-diol ( DMT… Click to show full abstract
Abstract In this work, we have compared the host abilities of closely related compounds (+)-(2 R ,3 R )-1,1,4,4-tetraphenylbutane-1,2,3,4-tetraol ( TETROL ) and (2 R ,3 R )-(−)-2,3-dimethoxy-1,1,4,4-tetraphenylbutane-1,4-diol ( DMT ) when these were recrystallized from single and mixed toluidine guests. Significant differences in host behaviour and selectivities were revealed and these were explained by means of single crystal diffraction experiments. Thermal analyses were used to determine the relative complex stabilities, and these data correlated exactly with the host selectivity orders for both TETROL and DMT .
