  甲苯作为黄药的新型载体—S-三氯和二氯甲基黄药的制备，使用和替代

  摘要：

  甲苯已被确定为黄药的新型载体。事实证明，它们相应的片段化前体在自由基基团转移反应中可有效发挥作用。作为实例，可以制备，分离和进一步用于烯烃的自由基加成中空前的S-三/二氯甲基黄原酸酯。它们的前体（去芳香化的甲苯，其一端接有三/二氯甲基，而另一端接有二硫代羰基）也可直接用于两个基团向烯烃的转移。因此，通过前体的自由基引发的断裂而重新芳香化损失的甲苯给黄原酸酯的化学带来了新的机会，在此以新的S -tri /二氯甲基黄原酸酯的分子间加成为例。

• Vegetation mapping of a tropical freshwater swamp in the Northern Territory, Australia: A comparison of aerial photography, Landsat TM and SPOT satellite imagery

  The tropical wetland environments of northern Australia have ecological, social, cultural and economic values. Additionally, these areas are relatively pristine compared to the many other wetland environments in Australia, and around the world, that have been extensively altered by humans. However, as the remote northern coastline of Australia becomes more populated, environmental problems are beginning to emerge that highlight the need to manage the tropical wetland environments. Lack of information is currently considered to be a major factor restricting the effective management of many ecosystems and for the expansive wetlands of the Northern Territory, this is especially the case, as these areas are generally remote and inaccessible. Remote sensing is therefore an attractive technique for obtaining relevant information on variables such as land cover and vegetation status. In the current study, Landsat TM, SPOT (XS and PANT) and large-scale, true-colour aerial photography were evaluated for mapping the vegetation of a tropical freshwater swamp in Australia's Top End. Extensive ground truth data were obtained, using a helicopter survey method. Fourteen cover types were delineated from 1:15 000 air photos (enlarged to 1:5000 in an image processing system) using manual interpretation techniques, with 89% accuracy. This level of detail could not be extracted from any of the satellite image data sets, with only three broad land-cover types identified with accuracy above 80%. The Landsat TM and SPOT XS data provided similar results although superior accuracy was obtained from Landsat, where the additional spectral information appeared to compensate in part for the coarser spatial resolution. Two different classification algorithms produced similar results.
