摘要:介绍了一种薄通道平面电极发射器装置,用于研究和控制电喷雾离子源中发射器电极上分析物的电化学氧化.对于不是特别容易氧化的分析物,平面电极装置的分析功能与使用更常见的不锈钢管电极的发射器系统类似.对于较易氧化的分析物,该装置可通过简单快速地改变电极材料,电极面积,电极覆盖层,电极上方的通道高度或溶液流速,实现接近 100% 的氧化效率或完全消除分析物氧化.与使用管状电极相比,平面电极发射器系统在改变电极面积和材料性质以及改变分析物向电极表面的质量传输方面具有更大的灵活性.这些参数中的每一个都对电化学反应的控制至关重要,使用这种发射器电极配置可以很容易地对其进行研究或利用.

标题 :Synthesis of indoles by dehydrogenation of indolines

摘要:##STR1## By dehydrating indolines or their salts, the corresponding indoles having formula (I) are obtained. In the formula, R 1 and R 3 represent independently from each other hydrogen or alkyl groups with 1 to 4 C atoms, R 2 stands for hydrogen, a methyl or a carboxyl group, R 4 and R 5 represent independently from each other hydrogen, amino groups, hydroxy groups, alkyl groups with 1 to 4 C atoms or alkoxy groups with 1 to 4 C atoms, or, in case R 4 and R 5 are bound to adjacent C atoms, both residues may also represent together an alkylene dioxy group with 1 to 4 C atoms. This process allows high yields of very pure indoles to be produced.

摘要:Provided in the present invention are a synthesis method for 5,6-dihydroxyindole and an intermediate thereof. The method comprises: by using a hydrohalide salt or other acid salts (IC241-01) of 5,6-dihydroxyindoline as raw materials, sequentially protecting the heteroatom nitrogen and phenolic hydroxyl, so as to obtain an intermediate compound 1-benzyloxycarbonyl-5,6-dibenzyloxyindoline (IC241-03); then performing an oxidation reaction to obtain an intermediate compound 1-benzyloxycarbonyl-5,6-dibenzyloxyindole (IC241-04); and in the presence of trace amounts of an antioxidant and a polymerization inhibitor, performing catalytic hydrogenation to remove the protecting group, so as to obtain 5,6-dihydroxyindole (DHI). The method in the present invention involves reactions with mild conditions, can stably realize mass production, uses feasible raw materials, and achieves controllable cost and good process reproducibility. In addition, on the basis of the synthesis strategy of removing the protecting group in the final step, and because of the functions of the trace amounts of the antioxidant and the polymerization inhibitor, the target product 5,6-dihydroxyindole (DHI) has the comprehensive advantages of light color, high purity, convenient storage and subsequent use, etc.
