In this work we report the preparation of mixtures of several alkyl glyceryl ethers, as hydrogen bond donor compounds, with two ammonium salts, choline chloride and N,N,N-triethyl-2,3-dihydroxypropan-1-aminium chloride. The stability of the mixtures at different molar ratios and temperatures has been evaluated in order to determine the formation of lowmelting mixtures. Liquid and stable mixtures have

Efficient regio- and stereoselective ring opening of epoxides with alcohols, acetic acid and water catalyzed by ammonium decatungstocerate(IV)
Epoxides can be cleaved in a regio- and stereoselective manner under neutral conditions with alcohols and acetic acid in the presence of catalytic amounts of decatungstocerate(IV) ion, ([CeW10O36]8−), affording the corresponding β-alkoxy and β-acetoxy alcohols in high yields. In water, ringopening of epoxides occurs with this catalyst to produce the corresponding diols in good yields.
可以在中性条件下用醇和乙酸在催化量的decatungstocerate(IV)离子([CeW 10 O 36 ] 8-)存在下,以区域和立体选择性的方式裂解环氧化合物,得到相应的β-烷氧基和β-乙酰氧基醇收率高。在水中,该催化剂会发生环氧化物的开环反应,从而以高收率生产出相应的二醇。
