Chemically Modified -Cyclodextrins as Supramolecular Carriers in the Biphasic Palladium-Catalyzed Cleavage of Allylic Carbonates: Activity Enhancement and Substrate-Selective Catalysis

Biphasic aqueous organometallic catalysis promoted by cyclodextrins: Can surface tension measurements explain the efficiency of chemically modified cyclodextrins?

“…Finally, it should be noticed that the methylated CDs areas are smaller that those of hydroxypropylated CDs (Table 2 compared entry 1 with entries 2, 3 and 4; compared entry 6 with entries 7 and 8), confirming less hindered structures of methylated CD compared to hydroxypropylated CDs. Although we have reported the efficiency of numerous α-or β-CD derivatives in hydroformylation and Tsuji-Trost reactions [36,42], supplementary catalytic experiments were required to correlate all our surface excess values with catalytic results. Indeed, the effects of DIME-α-CD (10.8), RAME-α-CD (15.0) and CRYSMEB-β-CD (5.0) have never been investigated in the hydroformylation and Tsuji-Trost reactions.…”

Design and synthesis of a 3′- O -allyl photocleavable fluorescent nucleotide as a reversible terminator for DNA sequencing by synthesis

“…For application in SBS, it is important to ensure that complete chemical cleavage of the 3Ј-O-allyl group can be rapidly and specifically carried out while leaving the DNA intact. TPPTS has been widely used as a ligand for Pd-mediated deallylation under aqueous conditions (28)(29)(30), whereas an active Pd catalyst can be generated from Na 2 PdCl 4 and an appropriate ligand (31,32). Thus, we investigated a water-soluble Pd catalyst system generated from Na 2 PdCl 4 and TPPTS for deallylation of the 3Ј-O-allyl-modified DNA product.…”

Kinetics of the oxidative degradation of thionine dye by hydrogen peroxide catalyzed by supported transition metal ions complexes

“…This water‐soluble molecule has a large intramolecular cavity, which is essentially hydrophobic and can host a large variety of organic molecules. This outstanding property has been utilized for a long time in the food, cosmetic, and pharmaceutical industries and still finds new potential applications 52. The inclusion of TH into β‐CD has been studied 53.…”
