β-CD assisted dissolution of quaternary ammonium permanganates in aqueous medium

Green and Efficient: In Situ Oxidation Kinetics of Some Tailor-Made γ-Styrylpyridinium Dyes in Aqueous Medium Using the β-CD-CTAP Complex

“…During the dissolution of CTAP in aqueous medium in the presence of β-CD, a linear increase in the solubility of CTAP as a function of β-CD concentration occurs, which is reflected through an A L type phase–solubility profile, indicating the formation of 1:1 soluble inclusion complexes of β-CD-CTAP . However, there might have been the formation of some non-inclusion complexes as well.…”

“…Recently, we have reported the inclusion complexation of CTAP with β-CD producing a new functionalized oxidant (β-CD-CTAP) in water medium . Absence of tight ion pairing in this medium makes CTAP more stable compared to in any of the organic media.…”

UV–Vis spectrophotometric studies of self-oxidation/dissociation of quaternary ammonium permanganates (QAP) – impact of solvent polarity

“…Such a difference in the rates of self-oxidation/ dissociation of the substrates may be due to the difference in their structural geometry. Since CTAP undergoes self-organization due to its large hydrophobic cleft, which is not possible in case of TBAP [29], it stabilizes itself in various solvent media, which is not feasible in case of TBAP. This results in a remarkable difference in their rates of self-oxidation/dissociation.…”

“…Though the event of self-oxidation, not observed in case of CTADC or CTACN, makes CTAP a suicidal oxidant, this oxidant still maintains its versatility among most of the workers due to the absence of any poisonous and free radical generating characteristics [26][27][28] unlike CTADC and CTACN, respectively. When used in aqueous b-cyclodextrin (b-CD), CTAP behaves as an excellent oxidant with lower degree of self-oxidation, higher degree of stability and possesses the capability of oxidizing water soluble inorganic and organic substrates in aqueous medium [29].…”

Inclusion Complex of Docetaxel with Sulfobutyl Ether β-Cyclodextrin: Preparation, In Vitro Cytotoxicity and In Vivo Safety

“…SBE-β-CD is non-toxic and biocompatible CD derivatives which exhibits solubility and complexing abilities greater than those of the parent β-CD. Meanwhile, the four-carbon butyl chain of SBE-β-CD coupled with the repulsion of the end group’s negative charge gives an extremely hydrophilic exterior surface and an extended hydrophobic cavity, which compared with other CD derivatives [ 13 , 14 ].…”
