• Reductive Coupling of Aldehydes by H2S in Aqueous Solutions, a CC Bond Forming Reaction of Prebiotic Interest
  作者：Mohammed Kajjout、Yanek Hebting、Pierre Albrecht、Pierre Adam

  DOI：10.1002/cbdv.201100124

  日期：2012.4

  We report here a novel reductive coupling reaction of conjugated, non- or poorly enolizable aldehydes induced by H(2) S and operative in aqueous solutions under prebiotically relevant conditions. This reaction leads from retinal to β-carotene, and from benzylic aldehydes to the corresponding diarylethylenes. This novel reaction also opens a new potentially prebiotic pathway leading from glyoxylic acid

  我们在这里报告了由H（2）S诱导和水溶液在益生元相关条件下有效的共轭，非或难烯化醛的新型还原性偶联反应。该反应从视网膜到β-胡萝卜素，从苄基醛到相应的二芳基乙烯。这种新颖的反应还开启了一条新的潜在的益生元途径，从乙醛酸到还原性三羧酸循环中涉及的各种化合物。益生元感兴趣的这种C-C键形成反应可能在热液喷口的富含硫化物的环境中有效，据推测这是有机化学进化第一步的可能场所。

  A process of stabilizing bleaching agents in a detergent composition using a nonphosphorus-containing biodegradable stabilizer. The process involves incorporating into a detergent composition containing a bleaching agent, a biodegradable compound of the formula ##STR1## in which m is NR' or sulfur; X is SO.sub.3 H or COOH; Y is hydrogen, SO.sub.3 H or COOH; R and R' are, independently, hydrogen, --CH(Z)CH.sub.2 (Z'), --CH(Z)CH(Z')(Z") or --CH.sub.2 COOH; and Z, Z' and Z" are, independently, hydrogen, OH, SO.sub.3 H or COOH; or a sodium, potassium or ammonium salt thereof, in an amount sufficient to stabilize the bleaching agent. Novel detergent compositions containing the biodegradable bleach stabilizers are also disclosed.

  公开（公告）日：2008-07-30

  An upper layer-forming composition formed on a photoresist while causing almost no intermixing with the photoresist film and a photoresist patterning method are provided. The upper layer-forming composition is stably maintained without being eluted in a medium such as water during liquid immersion lithography and is easily dissolved in an alkaline developer. The upper layer-forming composition covers a photoresist film for forming a pattern by exposure to radiation. The composition comprises a resin dissolvable in a developer for the photoresist film and a solvent in which the resin is dissolved. The solvent has a viscosity of less than 5.2 x 10-3 Pa·s at 20°C. In addition, the solvent does not cause intermixing of the photoresist film and the upper layer-forming composition. The solvent contains an ether or a hydrocarbon.
