1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5) is a member of crown ether Ligands. Crown-ethers are macrocyclic polyethers capable of forming host-guest complexes, especially with inorganic and organic cations. Crown-ethers can incorporate protonated primary amine compounds by formation of ion-dipole bonds with the oxygen atoms of the chiral selector. Crown-ethers have been widely used for the separation of several pharmaceuticals both in aqueous and non-aqueous media. Recommanded Product: 1,4,7,10,13-Pentaoxacyclopentadecane

The article was titled 《Phosphorus-Atom Transfer from Phosphaethynolate to an Alkylidyne》.Recommanded Product: 1,4,7,10,13-Pentaoxacyclopentadecane The article contains the following contents:

A low-spin and mononuclear V complex, (Menacnac)V(CO)(η2-PCtBu) (2) (Menacnac- = [ArNCMe]2CH, Ar = 2,6-iPr2C6H3), was prepared upon treatment of the V neopentylidyne complex (Menacnac)VCtBu(OTf) (1) with Na(OCP)(diox)2.5 (diox = 1,4-dioxane), while the isoelectronic ate-complex [Na(15-crown-5)]{([ArNC(CH2)]CH[CMeNAr])V(CO)(η2-PCtBu)} (4), was obtained via the reaction of Na(OCP)(diox)2.5 and ([ArNC(CH2)]CH[CMeNAr])VCtBu(OEt2) (3) in the presence of crown-ether. Computational studies suggest that the P-atom transfer proceeds by [2+2]-cycloaddition of the PC bond across the VCtBu moiety, followed by a reductive decarbonylation to form the V-CO linkage. The nature of the electronic ground state in diamagnetic complexes, 2 and 4, was further studied both theor. and exptl., using a combination of d. functional theory (DFT) calculations, UV/visible and NMR spectroscopies, cyclic voltammetry, x-ray absorption spectroscopy (XAS) measurements, and comparison of salient bond metrics derived from X-ray single-crystal structural characterization. In combination, these data are consistent with a low-valent V ion in complexes 2 and 4. This study represents the 1st example of a metathesis reaction between the P-atom of [PCO]- and an alkylidyne ligand.1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5Recommanded Product: 1,4,7,10,13-Pentaoxacyclopentadecane) was used in this study.
