Regioselective halogenation of primary alcohol groups of cyclodextrins with halomethylenemorpholinium halides Vilsmeier-Haack reagents was written by Chmurski, K.;Defaye, J.. And the article was included in Polish Journal of Chemistry in 1999.Recommanded Product: 53784-83-1 This article mentions the following:
Per(6-bromo-6-deoxy)cyclomalto-hexaose, -heptaose, and -octaose and the corresponding per(6-chloro-6-deoxy) derivatives were prepared in high yield by reaction of bromomethylenemorpholinium bromide or chloromethylenemorpholinium chloride, resp., with cyclomaltohexaose, cyclomaltoheptaose and cyclomaltooctaose in DMF. In the experiment, the researchers used many compounds, for example, Heptakis(6-Bromo-6-Deoxy)-灏?Cyclodextrin (cas: 53784-83-1Recommanded Product: 53784-83-1).
Heptakis(6-Bromo-6-Deoxy)-灏?Cyclodextrin (cas: 53784-83-1) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon鑱砨romine bond is electrophilic in nature. The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.Recommanded Product: 53784-83-1
