Inclusion Complex Formation,pounds are included in the cavity of cyclodextrins (host) [20, 65–67]. Guest compounds range from polar reagents such as acids, amines, small ions such as ClO., SCN., and halogen anions [68] to highly apolar aliphatic and aromatic hydrocarbons and even rare gases [69]. Inclusion complexes can be for

Conclusion,eospecific, complexing of reactants before reaction per se occurs. The cyclodextrins are the first organic compounds found that show the ability to complex other organic compounds. Their stereospecificity is limited, although they do exhibit stereospecific reactions. As noted above, they do catalyze

Then came the realization that enzymes which are highly efficient ca­ talysts, work by way of prior complexation, often stereospecific, which is then followed by chemical reaction. Thus, systems that exhibit "host-guest" relationships, i.e., that show complexing are being looked at a

Inclusion complexes can be formed either in solution or in the crystalline state. Water is usually used as solvent, although inclusion complex formation also takes place in dimethyl sulfoxide and in dimethyl formamide [70].
