  The reaction of condensation of furfural with mercaptoacetic acid esters

  摘要：

  The condensation reaction of furfural with various mercaptoacetic acid esters was studied. The reaction products were tested for their corrosion protective properties in M-16 cylinder oil used for marine diesel engines. It was found that the resulting 2-di(alkoxycarbonylmethylthio)methylfuranes at 2% concentration completely suppress corrosion of lead plates.

• Preparation of Brominated 2-Alkoxythiophenes via Oxidation and Etherification of 2-Thienyltrifluoroborate Salts

  日期：2012.10.5

  The synthesis of ring brominated long-chain 2-alkoxythiophenes is reported, involving mild (Oxone) oxidation of readily prepared 2-thienyltrifluoroborate salts followed by Mitsunobu etherification. Both procedures are operationally straightforward and use inexpensive reagents. Using this approach, several novel mono- and dibrominated octyloxythiophenes with previously elusive substitution patterns

  据报道，环溴化长链2-烷氧基噻吩的合成涉及容易制备的2-噻吩基三氟硼酸盐的温和（Oxone）氧化，然后进行Mitsunobu醚化。两种方法在操作上都很简单，并且使用廉价的试剂。使用这种方法，制备了几种新颖的具有以前难以捉摸的取代方式的单溴和二溴辛基氧基噻吩。一种这样的化合物被修饰为新型的5-烷氧基噻吩并[3,2- b ]噻吩-2-羧酸酯，这标志着该化合物家族的首次合成。
