COMPLEX FORMATION OF CYCLOMALTO-OCTAOSE WITH TETRABROMOPHENOLPHTHALEIN AND SOME RELATED COMPOUNDS

The interactions of cyclomalto-octaose (γ-cyclodextrin) with some phthalein-type acid-base indicators have been investigated photometrically.Bromine substituents enhance the formation of complexes and tetrabromophenolphthalein forms the most stable complex (K 6.0 x 1E3).This stability and other phenomena suggest that the host and guest are involved in a three-site interaction.

1-Benzyl-4-aza-1-azoniabicyclo[2.2.2]octane tribromide as a regenerable and useful reagent for bromination of phenols under mild conditions

1-Benzyl-4-aza-1-azoniabicyclo[2.2.2]octane tribromide has been examined over several phenolic compounds under mild conditions. The reaction gives brominated phenols in good to excellent yields. Straightforward work-up of the reaction yields pure products in several cases.
