Abstract
Per(6-bromo-6-deoxy)cyclomalto-hexaose, -heptaose, and -octaose and the cor responding per(6-chloro-6-deoxy) derivatives were prepared in high yield by reaction of bromomethylenemorpholinium bromide or chloromethylenemorpholin ium chloride, respectively, with cyclomaltohexaose, cyclomaltoheptaose and cyclomaltooctaose in dimethylformamide.
