    日期:2011.5
    NH4AcMIMOH), were prepared and used as catalysts for catalytic synthesis of propylene glycol ether via reaction of propylene oxide (PO) with methanol under mild reaction conditions. KAcMIMOH exhibited outstanding catalytic performance with 94.2% of conversion of PO and 99.1% of selectivity to 1-methoxy-2-propanol (MP-2) at 60°C and ambient pressure for 4 h. However, AcMIMCl-FeCl3 showed a good catalysis performance

    (Poly)glycerol monoethers were synthesized in good yield and selectivity by the catalytic reductive alkylation of glycerol, diglycerol, and triglycerol with readily available, cheap and/or bio‐sourced carboxylic acids. The reaction was catalyzed by 1 mol % of Pd/C under 50 bar H2 using an acid ion‐exchange resin as a recyclable cocatalyst. The catalytic system was recycled several times, and a mechanism

    Crystalline Mo–V–O oxides have been used as a catalyst for the hydrolysis and alcoholysis of propylene oxide to diols and ethers, respectively. Relationships between the active crystal facet, the acidity of Mo–V–O catalysts and the activity have been established. Our results indicate that the a–b plane is the active facet for the hydrolysis reaction.

    A process for the preparation of (R)-1-(2,3-difluoro-6-nitrophenoxy)-propan-2-ol, which is a useful intermediate in the synthesis of the widely used antibiotic Levofloxacin is provided. A process for the preparation of (R)-1-(2,3-difluoro-6-nitrophenoxy)-2-trimethylsiloxypropane is also described. The process includes the ring opening of (R)-propylene oxide with 2,3-difluoro-6-nitrophenyl trimethylsilyl ether in the presence of an optically active Co(salen) catalyst. The trimethylsilyl group of the reactant is transferred to the product aryloxy alcohol, which serves to protect the secondary alcohol in situ. Upon isolation, the trimethylsilyl group is removed and the resulting regioisomeric mixture purified to yield the desired (R)-1-(2,3-difluoro-6-nitrophenoxy)-propan-2-ol in high purity and yield.
