Oxidative Cyclization of Lithium 4-Ethoxy-1,1,1-trifluoro-4-oxobut-2-en-2-olate

Diethyl 2,5-dihydroxy-2,5-bis(trifluoromethyl)tetrahydrofuran-3,4-dicarboxylate has been synthesized for the first time by reaction of lithium 4-ethoxy-1,1,1-trifluoro-4-oxobut-2-en-2-olate with manganese(III) acetate. The structure of its (2S*3S*4S*5S*) stereoisomer has been confirmed by X-ray analysis.

Anomalous non-prussian blue structures and magnetic ordering of K 2MnII[MnII(CN)6] and Rb 2MnII[MnII(CN)6]

The reaction of MnII and KCN in aqueous and non-aqueous media leads to the isolation of three-dimensional (3-D) Prussian blue analogues, K2Mn[Mn(CN)6] (1a-d, 1e, respectively). Use of RbCN forms Rb2Mn[Mn(CN)6] (2). 1 and 2 are isomorphic {monoclinic, P21/n: 1 [a = 10.1786(1) A, b = 7.4124(1) A, c = 6.9758(1) A, β = 90.206(1)°]; 2 [a = 10.4101(1) A, b = 7.4492(1) A, c = 7.2132(1) A, β = 90.072(1)°]}, with a small monoclinic distortion from the face centered cubic (fcc) structure that is typical of Prussian blue structured materials that was previously reported for K2Mn[Mn(CN)6]. Most notably the average Mn-N-C angles are 148.8° and 153.3° for 1 and 2, respectively, which are significantly reduced from linearity. This is attributed to the ionic nature of high spin MnII accommodating a reduced M-CN-M0 angle and minimizing void space. Compounds 1a, b have a sharp, strong.OH band at 3628 cm-1, while 1e lacks a v OH absorption. The vOH absorption in 1a, b is attributed to surface water, as use of D2O shifts the.OH absorption to 2677 cm-1, and that 1a-e are isostructural. Also, fcc Prussian blue-structured Cs2Mn[Mn(CN)6] (3) has been structurally [Fm3hm: a = 10.6061(1) A] and magnetically characterized. The magnetic ordering temperature, Tc, increases as K+ (41 K) + (34.6 K) + (21 K) for A2Mn[Mn(CN)6] in accord with the increasing deviation for linearity of the Mn-N-C linkages [148.8 (K+) +)], decreasing Mn(II) · · · Mn(II) separations [5.09 (K+) > 5.19 (Rb+) > 5.30 A° (Cs+)], and decreasing size of the cation (increasing electrostatic interactions). Hence, the bent cyanide bridges play a crucial role in the superexchange mechanism by increasing the coupling via shorter Mn(II) 3 3 3 Mn(II) separations, and perhaps enhanced overlap. In addition, the temperature dependent magnetic behavior of K4[MnII(CN) 6] · 3H2O is reported.

Stabilizing Vegetable Oils And Methods Of Making Same

A method for modifying ethylenic unsaturation in a triglyceride. One or more unsaturated fatty acyl moieties present in the triglyceride are substituted with a lactone or ketone moiety via a electron donor mediated reaction. The resulting reaction products are useful, for example, as formulations for lubricants, hydraulic fluids, dielectric fluids, and intermediates for polymer synthesis.
