Several small, lipophilic rheniumcomplexes form inclusion complexes with native beta-cyclodextrin (beta-CD) and beta-CD dimers. Association constants larger than 10(9)M(-1) were obtained using dimers. The use of beta-CD also enabled the synthesis of these rheniumcomplexes in water, in excellent yields, through complexation of the otherwise insoluble corresponding ligands. The influence of the reaction
New yellow cationic dyes of the formula ##STR1## ARE DISCLOSED WHEREIN X represents hydrogen or halogen, R represents an optionally substituted alkyl group or cycloalkyl group, Or --CH.sub.2 -- if this is linked with the phenylene group in the o-position with respect to the oxygen bond to form a 6-membered ring and n represents 1, R.sub.1 represents an unsubstituted, straight-chain or branched-chain alkyl group having 1 to 5 carbon atoms, R.sub.2 represents a substituted, or preferably unsubstituted, straight-chain or branched-chain alkyl group having 1 to 5 carbon atoms, N represents the numbers 1 or 2, and An represents an anion, which dyes are useful for dyeing and printing of textile material especially polyacrylonitrile.
