Abstract
NEW MATERIAL:An A,C-benzophenone-3,3'-disulfonate-capped compound of β- cyclodextrin, represented by formulaI, wherein R is a group of formula II.
USE: A material for the production of a bifunctional cyclodextrin useful as a hydrolysis catalyst, decarboxylation catalyst or reduction catalyst and as a stabilizing agent for pharmaceuticals and agricultural chemicals.
PREPARATION: The compound of formulaIis prepared by dissolving β-cyclodextrin in about 8W100 times by weight of a solvent such as pyridine or dimethylfomaldehyde, adding thereto at least 0.5 eq., per eq. β-cylodextrin, benzophenone-3,3'-disulfonyl halide and reacting the mixture at about 10W100°C.
