D. Armspach et D. Matt, Metal-capped alpha-cyclodextrins: the crowning of the oligosaccharide torus with precious metals, CHEM COMMUN, (12), 1999, pp. 1073-1074
The synthesis of diphosphino alpha-cyclodextrins (alpha-CDs) and their capp
ing by transition metals are described; one of the complexes has been teste
d in biphasic catalytic hydroformylation.
