Preparation and properties of inclusion compounds of transition metal complexes of cyclo-octa-1,5-diene and norbornadiene with cyclodextrins

Abstract

2 : 1 (cyclodextrin : guest) inclusion compounds were obtained in high yields by the treatment of β-cyclodextrin (β-CD) with [(L)RhCl]₂(L = norbornadiene or cyclo-octa-1,5-diene, cod) and 1:1 inclusion compounds were obtained by the reaction of β-CD with (cod)PtX₂(X = Cl, Br, or I) in high yields, while γ-CD formed 1:1 inclusion compounds with (cod)PtX₂(X = Br or I); the formation of inclusion compounds is selective.
