  Diprotodecarboxylation Reactions of 3,4-Dialkoxythiophene-2,5-dicarboxylic Acids Mediated by Ag₂CO₃ and Microwaves

  摘要：

  An efficient and rapid method is reported to obtain 3,4-dialkoxythiophenes from 3,4-dialkoxythiophene-2,5-dicarboxylic acids through a diprotodecarboxylation reaction with Ag2CO3/AcOH as a catalytic system and microwave heating in dimethylsulfoxide (DMSO) as solvent. This methodology lets us obtain for the first time good performance with thiophenes bearing strong electron-donating groups such as alkoxides. This methodology eliminates the usage of harmful quinoline as solvent, as well as the long reaction times typically used (12-18h) to obtain the 3,4-dialkoxythiophenes. The reaction of 7 diacids showed good yields (60-89%) following 20min of microwave heating in a temperature range of 120-150 degrees C. [Supplementary materials are available for this article.

• Versatile Superhydrophobic Surfaces from a Bioinspired Approach
  作者：Mélanie Wolfs、Thierry Darmanin、Frédéric Guittard

  We report the surface wettability and morphology of conductive polymer films obtained by electrodeposition of poly(3,4-ethylenedioxythiophene) (i.e., PEDOT) derivatives containing an alkyl chain (PEDOTHn with n = 4, 6, 8, 10, and 12) or a phenyl (PEDOTPh) group in the 2-position. Even if the general approach in the literature is the use of highly fluorinated tail to reach superhydrophobic materials, we point out that versatile surfaces (from hydrophilic to superhydrophobic) can be obtained, in one step, without any fluorinated chemistry. Indeed, superhydrophobic surfaces were formed, using Bu4NPF6 and acetonitrile as electrolyte, by electrodeposition of PEDOT derivatives substituted with n-C10H21 and n-C12H25 chains, while the polymer films substituted with n-C8H17 and n-C6H13 were hydrophobic and those substituted with n-C4H9 and phenyl were hydrophilic. In the PEDOTHn series, the polymer films were structured only from n-C8H17, which proves the influence of long alkyl chains on both the surface wettability and the surface morphology due to the increase in polymer insolubility. By changing acetonitrile by dichloromethane, as solvent of electropolymerization, it is possible to produce smooth surfaces and as a consequence to determine the chemical and physical parts of the contact angles as well as roughness factors or air fractions following the Wenzel and Cassie-Baxter theories. By changing the salt for the electrodeposition, it also was possible to reach superhydrophobic surfaces even with short alkyl chains as well as without alkyl chains but using perfluorinated salts. In this work the mechanism to reach structured surfaces is also discussed. This work contributes to the formation of bioinspired superhydrophobic surfaces.
