The complexation of mustard gas Cl(CH(2))(2)S(CH(2))(2) Cl, HD, yperite) and of ethers and thioethers derivatives by cyclodextrins: natural alpha-cyclodextrin (ACD) and substituted B-cyclodextrins was studied by NMR. A 1/1 stoechiometry was found in all cases, while affinity constants were found relatively weak (from 5 M(-1) to 100 M(-1)). However, these results show that chelation of HD by cyclodextrins can be reasonably expected, especially if chemical modifications provide stronger affinity constants.
