A mixed ionic liquid system has been developed for the efficient catalysis of CO2 addition to aliphatic epoxides without involving any transition metal catalysts or other additives. The ionic liquid integrated with pyridinium and pyrrolidinium groups (1¡¤(Br)3) together with a non-polar ionic liquid (3¡¤(Ntf)2) effectively transformed non-polar aliphatic epoxides to cyclic carbonates by the reaction with CO 2 under mild CO2 pressure (3.0 MPa) and reaction temperature (80 C). The presence of 3¡¤(Ntf)2 remarkably improved the catalytic activity of 1¡¤(Br)3 towards non-polar epoxides by increasing the miscibility of catalyst with the substrates. The mixed ionic liquid system is robust enough to be recycled without any significant loss of catalytic activity. GC-MS studies were performed to reveal the reaction pathways to the cyclic carbonates and a feasible model accounting for the effective CO2 activation in the ionic liquid system was proposed using density functional theory (DFT) calculations.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 499-40-1, help many people in the next few years., Electric Literature of 499-40-1

The synthesis and crystal structure of two heteronuclear compounds stabilized by four dipyridylamide (dpa) ligands is reported. Cu 2Pd(dpa)4Cl2 (1) and Cu2Pt(dpa) 4Cl2 (2) exhibit an approximate D4 symmetry and a linear metal framework. They are structurally similar to the homotrinuclear complexes M3(dpa)4L2 already characterized with various transition metals (M = Cr, Co, Ni, Cu, Rh, Ru). With 26 metal valence electrons, they are also isoelectronic to the oxidized form of the tricopper complex [Cu3(dpa)4Cl2]+ (3), previously characterized and investigated by Berry et al.10 The magnetic properties and the EPR spectra of 1 and 2 are reported. The results for 1 are interpreted in terms of a weak antiferromagnetic interaction (2J = 7.45 cm-1 within the framework of the Heisenberg Hamiltonian H = -2JAB SASB) between the Cu(II) magnetic centers. For 2, the antiferromagnetic interaction sharply decreases to <1 cm-1. These properties are at variance with those of (3), for which a relatively strong antiferromagnetic interaction (2J = -34 cm -1) had been reported. DFT/UB3LYP calculations reproduce the decrease of the magnetic interaction from 3 to 1 and assign it to the role of the nonmagnetic metal in the transference of the superexchange coupling. However, the vanishing of the magnetic interaction in 2 could not be reproduced at this level of theory and is tentatively assigned to spin-orbit coupling.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.10034-20-5, Name is (2S,3R,4R,5S,6R)-6-(Acetoxymethyl)-3-aminotetrahydro-2H-pyran-2,4,5-triyl triacetate hydrochloride, molecular formula is C14H22ClNO9. In a Article£¬once mentioned of 10034-20-5, COA of Formula: C14H22ClNO9

Virtually complete regioselective galactosylation of the diol acceptor p-methoxyphenyl 6-O-benzyl-2-deoxy-2-tetrachlorophthalimido-beta-D- glucopyranoside (8) with the donor phenyl 2,3,4-tri-O-acetyl-6-O-benzyl-1- thio-beta-D-galactopyranoside (11) gave the lactosamine derivative 14, which was fucosylated with the donor 15 to give the Le(x) trisaccharide glycoside 2 after deprotection. Regioselective sialylation of the partially protected Le(x) trisaccharide triol 24 with the sialyl donor 25 gave, after deprotection, the SLe(x) tetrasaccharide glycoside 1. The overall yields of 2 and 1 from the monosaccharide starting materials 8, 11, 15, and 25 were 56% and 29%, respectively. In contrast to the virtually complete regio- and stereoselective galactosylation of 8, fucosylation with the benzyl-protected donor 15 gave the corresponding 1?3- and 1?4-linked disaccharides in a ratio of 3.6:1 (highly stereo- but not regioselective glycosylation), whereas fucosylation with acetyl-protected donor 18 gave a 2.2:1 beta/alpha-mixture of 4- O-linked disaccharides (highly regio- but not stereoselective glycosylation).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C14H22ClNO9, you can also check out more blogs about10034-20-5

Synthetic Route of 10343-06-3. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose. In a document type is Article, introducing its new discovery.

A series of novel guanidinoglycosides was successfully synthesized. This was accomplished with the use of Mitsunobu conditions as a strategy to convert the glycopyranose anomeric hydroxy group to give the corresponding substituted masked guanidines in high yields. Subsequent deprotection and coupling with Fmoc protected beta-amino acid, afforded a series of N,N?-substituted-methyl-isothioureas. Cleavage of Fmoc followed by concomitant cyclization was achieved with a catalytic amount of DBU to give the guanidinoglycosides.
