标题:从血红蛋白到单中心加氢催化剂
摘要:铁基单中心催化剂在实现高选择性化学过程方面具有巨大潜力,另外铁是一种富含地球的金属.它们在氧还原的电催化中被广泛探索,并在有机转化中显示出有前景的催化活性.特别是,Fen X @c 催化剂对于将硝基芳烃还原为芳香胺具有活性.然而,它们难以大规模生产,并且大多数制备方法都无法避免单点聚集.在这里,我们通过简单的两步过程从生物衍生化合物木糖和血红蛋白中制备了 Fen X @c 催化剂.由于血红蛋白天然含有 Fen X单中心,我们成功地将它们重新用于加氢催化中心,并在材料制备过程中避免了它们的聚集.通过像差校正透射电子显微镜和 X 射线吸收技术证明了它们的单点性质.它们被证明在将硝基芳烃转移氢化成苯胺方面具有活性,具有优异的底物选择性和可回收性,这在七个催化循环中保持的产率证明了这一点.我们还表明,Fen X @c 可用于通过还原/缩合串联制备 2-苯基苯并咪唑.我们的工作首次展示了生物质前体制备

标题:Preparation of azo pigments with low pcb content by coupling in the presence of olefins
发明人：RIEPER WOLFGANG
权利人:HOECHST AG
摘要:The production which is customary in practice of monoazo compounds based on dichloro- and trichloroanilines or disazo compounds of the chlorinated biphenyl series by conventional coupling methods meets with difficulties in that the resulting pigments are contaminated by traces of polychlorinated biphenyls. n According to the invention, it has now been found that by addition of water-soluble olefins of the type ##STR1## (R =H, alk or Oalk; X =--COOR 1 , --CONHR 2 or --NR 3 COR 4 ) n in the azo coupling, the side reactions which form PCBs can be decidedly suppressed during synthesis of the pigments.

标 题:Ring-opened purine compounds for labeling polynucleotides
发明人：MCCABE MEAD M
权利人:UNIV MIAMI
摘要:The invention provides methods for attaching detectable labels to the N 7 -formyl group, of imidazole ring-opened alkylated purines and purine derivatives, directly, through a linking group, or by subsequent derivatization of a blocking group. The invention provides simple and efficient methods for labeling polynucleotides. In addition, the invention provides derivatized ring-opened alkylated purines and purine derivatives, including reagents for chemical and enzymatic synthesis of detectably labeled polynucleotides.
