Increased interest in the trifluoromethoxy group in organic synthesis and medicinal chemistry has induced a demand for new, selective, general, and faster methods applicable to natural products and ...

However, the suitable weight ratio of Nb2O5:(H3PO2/PVA) for the blend performance (both mechanically and electrically) was x = 0.075, with a maximum ionic conductivity of 2.7× 10﹣3 S·cm﹣1 at 120°C.

Mix 4.2 g of sodium nitrite (NaNO2, CAS # 7362-00-0) and 20 ml of hypophosphorous acid (50%) (H3PO2, CAS # 6303-21-5) in 300 ml of water; Wash the area once with a paper towel soaked in ...

The glycerol/H3PO2 system can be easily recovered and reused in chemoselective 1,4-reductions for successive cycles without loss of efficiency. Additionally, under 1,4-reducing reaction conditions, ...

The direct intramolecular stereospecific substitution of the hydroxyl group in enantiomerically enriched secondary benzylic, allylic, propargylic, and alkyl alcohols was successfully accomplished by ...

Using a constant H3PO2/PVA weigh ratio of 0.25, it was found that the water content in the blended hydrogel membranes increased with increasing the filler Nb2O5 content, thus increasing the electrical ...
