A rearrangement of lithium alkoxide of 2-(1-hydroxyalkyl)-1-alkylcyclopropanol into lithium alkoxide of vic-diol was mediated with an organozincate complex.

The partially fluorinated oxo-alkoxide tungsten(VI) complexes WO(OR)4 [4; R = C(CH3)2CF3, 5; R = C(CH3)(CF3)2] have been synthesized as precursors for chemical vapour deposition (CVD) of WOx nanocrystalline material. Complexes 4 and 5 were prepared by salt metathesis between sodium salts of the fluoroalkoxides and WOCl4. Crystallographic structure analysis allows comparison of the bonding in 4 ...

Uric acid is an Analyte. Excess uric ─ hyperuricemia leads to gout and renal stones. Frabot noted that added alkaline tungstate solution developed intense blue colour. A colorimetric method widely utilized quantify depends on the reduction of chromogen sodium by produce a measurable colour change. The reaction route from initial products coloured compounds oxido-degradation organic substance ha...

A low-cost and facile route to the synthesis of bimetallic glycolato zirconate (Na2Zr(C2H4O2)3) and homometallic glycolato cerate (Ce(C2H4O2)), which can be used as alkoxide precursors for sodium zirconium oxide (and/or zirconia by sol–gel process) and ceria materials, has been developed from the reaction of inexpensive starting materials via the oxide one-pot synthesis (OOPS) process. Both com...

Submit Manuscript | http://medcraveonline.com PVC has significant defects due to its quick decomposition at temperature higher than 130°C [3-5]. This process results in a significant change in color, reducing the mechanical properties and the generated HCl exacerbates the decomposition of PVC, so the usage of PVC thermal stabilizers is inevitable [4,6]. Our group had synthesized pentaerythritol...

Yttria-doped zirconia powders" with an extremely small crystallite size (8 nm) and a narrow size distribution have been prepared by gel precipitation methods. Precipitation of an alkoxide solution in water ("alkoxide" synthesis) results in weaker agglomerates when compared with a precipitation of a metal chloride solution in ammonia ("chloride" synthesis). Both types of agglomerate are fracture...
