The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane, molecular formula is C10H20O5. In a Article,once mentioned of 33100-27-5, Quality Control of: 1,4,7,10,13-Pentaoxacyclopentadecane

A series of [M(L)(‘S2C’)] complexes (M = NiII, PdII, PtII) containing the carbene dithiolate ligand ‘S2C’2- = 1,3-imidazolidinyl-N, N?-bis(2-benzenethiolate)(2 – ) and various C and S co-ligands have been synthesized. When treated with KCN, n-butylisonitrile, the electron-rich olefin R2C=CR2 [ = bis(1,3-diphenylimidazolidine-2-ylidene)], LiMe, thiolates such as SEt-, SPh- or o-SC6H4NH2, and hydrogen sulfide, the parent complex [Ni(‘S2C’)]2 · DMF (1) yields the corresponding anionic or neutral [Ni(L)(‘S2C’)] complexes which were isolated as [K2(Kryptofix5)(THF)2(mu-OH2)][Ni(CN)(‘S2C’)] (2), [Ni(CNBu)(‘S2C’)] (3), [Ni(CR2)(‘S2C’)] (4), [Li(12-crown-4)2][Ni(CH3)(‘S2C’)] (5), [NBu4][Ni(SEt)(‘S2C’)] · THF (6), [Na(15-crown-5)][Ni(SPh)(‘S2C’)] (7), [Na(15-crown-5)][Ni(o-SC6H4NH2)(‘S2C’)] · 0.5THF (8), and [Na(15-crown-5)][Ni(SH)(‘S2C’)] (9). Analogous complexes of 9 have also been obtained with Pd (10) and Pt (11). The complexes were characterized by elemental analyses and the usual spectroscopic methods. X-ray structure determinations of 2, 3, 4, 6, 9 and 10 revealed that the [M(‘S2C’)] fragments are stereochemically very rigid, being little influenced by the different co-ligands L. The four-coordinate metal centers exhibit an approximately square-planar coordination geometry. The ‘S2C’2- ligands show a characteristic propeller-like twist resulting from positioning the C6 rings of the ‘S2C’ unit above and below the coordination plane. As evidenced by the molecular structures of 9 vs. 10, this twist can vary, and the ‘S2C’2- ligand is flexible enough to accommodate also larger metal ions than NiII. Complexes 9-11 belong to the rare cases of isolable SH complexes. The complexes 2-11 exhibit a remarkable thermal stability (4 is stable up to 220C), and the [M(‘S2C’)] fragments so far proved inert towards decomposition. When treated with Broensted acids, the general reactivity feature of all anionic [M(L)(‘S2C’)] complexes is release of HL and regeneration of the parent complexes [M(‘S2C’)]2. The methyl complex [Li(4-crown-4)2][Ni(CH3)(‘S2C’)] (5) is one of the rare examples in which a methyl ligand binds to an [NiS] center. While the parent complex [Ni(‘S2C’)]2 · DMF (1) proved unreactive towards CO, 5 readily inserts CO yielding the highly reactive acetyl derivative [Ni(COCH3)(‘S2C’)]-. This complex could not be isolated, but its formation was established by spectroscopic methods and by its subsequent reaction with PhSH yielding, among other products, the thioester CH3COSPh. The model character of this reaction sequence for acetyl-CoA synthesis catalyzed by CO dehydrogenases is discussed.

The behavior of crown- and phosphoryl-containing magnesium and zinc phthalocyaninates in solutions of synthetic and natural surfactants is studied. In a phosphate buffer (?? 7.4), zinc phthalocyaninate bearing oxy(pentyloxy)phosphoryl groups in peripheral substituents of the macrocycle is in aggregated state. According to absorption and fluorescence spectroscopy data, adding oppositely charged synthetic and natural surfactants leads to monomerization of this compound. The degree of monomerization of magnesium octa[(4´-benzo-15-crown-5)oxy]-phthalocyaninate in a microheterogeneous medium is affected by the concentration of sodium cholate and ionic strength. Fluorescence-active supramolecular gels based on sodium deoxycholate were prepared using phosphoryl-containing zinc phthalocyaninate.

Metathesis of “[Li(PyNSiMe3)(15C5)]” (15C5 = 15-crown-5 ether) with potassium tert-butoxide or rubidium 2-ethylhexoxide yields the two new amide complexes [{K(PyNSiMe3)(mu-15C5)}2] (3) and [{(Rb(mu-PyNSiMe3)(15C5)}2] (4). X-ray crystallography reveals 3 to be a ‘slipped’ centrosymmetric dimer, in which the crown ethers exhibit a bridging coordination mode via one crown oxygen from each crown to form a (KO)2 four-membered ring; the amide adopts a terminal chelating mode. In contrast, 4 is a centrosymmetric amido-bridged dimer with a transoid (RbN)2 core having additional bonding via bridging pyridyl groups; the crown ethers cap both ends of the dimer.

Binaphthyl stabilized Pt nanoparticles (Pt-BNP) have been synthesized, characterized, and utilized as an efficient heterogeneous catalyst for chemoselective reduction of nitroarenes at room temperature in water. Several sensitive functional groups like ketone, ester, acid, amide, halides, and nitrile were well tolerated in this chemoselective reduction. The Pt-BNP catalyst was quantitatively recovered without any major change in particle size and reactivity and then efficiently reused for five catalytic cycles.

A series of anionic chromium(III) thiocyanato complexes with metal crown ether cations have been prepared and characterized. These complexes have the form [Crown-M]2+[Cr(NCS)5(H2O)] 2- and [Crown-M]3+[Cr(NCS)6]3-, where M=Na+, K+, or NH4+ and crown represents the crown ether. The crown ethers are 15-crown-5, B-15-crown-5, 18-crown-6, DB-18-crown-6, and DB-24-crown-8, where B- and DB- stand for benzo- and dibenzo-, respectively. The complexes are stable for at least 20 h in the dark in dimethylformamide(DMF) or in acetonitrile, and they release thiocyanate slowly, k=(0.71-2.67)×10-9 mol/(L s) in acetonitrile in the dark. Photoanation of thiocyanate was observed for the complexes in DMF and in acetonitrile. The quantum yields of thiocyanate release in DMF and in acetonitrile are reported. The quantum yields were in the range 0.05 to 0.52 mol einstein-1 and were solvent and wavelength dependent. In general, larger quantum yields were observed in DMF than in acetonitrile.
