In the title compound, C12H19NO6, the six-membered 1,3-dioxane ring adopts a chair-like conformation. The seat of this chair, containing two O atoms, is essentially planar, with a maximum deviation of 0.0021 (12) Å. The five-membered oxolane ring cis-fused to the 1,3-dioxane ring adopts an envelope form. The bridgehead C atom at the flap, which is bonded to the tetra-substituted C atom of the o...
1,4-dioxane is an emerging contaminant that was used as a corrosion inhibitor with chlorinated solvents. Metal-activated persulfate can degrade dioxane but reaction kinetics have typically been characterized by a rapid decrease during the first 30 min followed by either a slower decrease or no further change (i.e., plateau). Our objective was to identify the factors responsible for this plateau...
Pseudonocardia sp. strain N23 is a 1,4-dioxane-degrading bacterium that is capable of utilizing 1,4-dioxane as the sole carbon and energy source. Here, we report the draft genome sequence of strain N23, with a size of 6.5 Mbp, to identify the genes associated with 1,4-dioxane degradation.
The title compound, C(15)H(14)O(4), was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and (Z)-3-phenyl-acryl-aldehyde in ethanol. The dioxane ring is in a sofa conformation with the C atom bonded to the two methyl groups forming the flap. With the exception of the flap atom and the methyl group C atoms, all other non-H atoms are essentially planar, with an r.m.s. deviation of 0...
In the title complex, [CdCl(2)(C(4)H(8)O(2))](n), two different Cd(II) ions are present, one in a general position and one with site symmetry 2. The Cd(II) ions are coordinated by two O atoms from two 1,4-dioxane ligands and four chloride anions in a slightly distorted octa-hedral geometry and is connected to neighboring Cd(II) ions by two bridging chloride anions, generating infinite linear ch...
In the title compound, C(12)H(16)O(4), the 1,3-dioxane ring adopts a chair conformation; the 2-phenyl substitutent occupies an equatorial position. Adjacent mol-ecules are linked by O-H⋯O hydrogen bonds into a chain.
The solubilities of amino acids, diglycine, and triglycine have been measured in water and aqueous ethanol as well as dioxane solutions. Free energies of transfer of amino acid side chains and backbone peptide units from water to ethanol and dioxane solutions have been calculated from these data. The results show the similarity between the ‘effects of ethanol and dioxane on the stability of tho...
Anhydrous thorium tetrachloride complexes ThCl(4)(DME)(2), ThCl(4)(1,4-dioxane)(2), and ThCl(4)(THF)(3.5) have been easily accessed from inexpensive, commercially available reagents under mild conditions and serve as excellent precursors to a variety of thorium(iv) halide, alkoxide, amide and organometallic compounds.
