Polypnictogen-transfer reagents

多砷化合物和多磷化合物代表了当前感兴趣的重要类别的化合物，特别是因为它们通过等瓣和对角关系显示出与相应有机化合物的强结构关系，但表明它们的反应性存在相当大的差异。由于这些类别的物质通常是通过使用黄色砷或白色磷进行还原合成的，在许多合成实验室中，只能根据其毒性和对氧和光的极端敏感性来限制处理，因此有必要开发用于En单位（E = P，As）的合适的储存和转移试剂。该项目的目标是合成具有丰富元素单元的新型转移试剂，其可以以简单的方式进行处理。使用这些富含En的起始材料，将实现获得过渡金属以及主族元素的多砷和多磷衍生物，其然后将作为前所未有的富含元素的杂芳族化合物、杂原子笼化合物和聚合物而存在。使用的As4和P4转移试剂，这可以在环境温度和以下的替代使用，将打开访问到新的亚稳态类的化合物含有迄今未知的En结构基序。除了生成新的主族元素和过渡金属化合物外，还针对新的砷和磷改性物的合成。

Polyarsenic and polyphosphorus compounds represent important classes of chemical compounds that are of current interest, especially as they show a strong structural relation to respective organic compounds via the isolobal and diagonal relationship, but indicate considerable differences regarding their reactivity. As these classes of substances are usually preparatively synthesized by using yellow arsenic or white phosphorus, which in many synthetic laboratories can be handled only restrictedly based on their toxicity and extreme sensitivity towards oxygen and light, it is necessary to develop suitable storage and transfer reagents for En units (E = P, As). Target of the project is the synthesis of novel transfer reagents with element rich units, which can be handled preparatively in a simple manner. Using these En rich starting materials, the access to polyarsenic and polyphosphorus derivatives of the transition metals as well as the main group elements will be realized, which then will be exist as unprecedented element rich heteroaromates, heteroatom cage compounds and polymeric compounds. The use of As4 and P4 transfer reagents, which can be preparatively used at ambient temperatures and below, will open the access to new metastable classes of compounds containing hitherto unknown En structural motifs. Besides the generation of new main group element and transition metal compounds the synthesis of new arsenic and phosphorus modifications is targeted.
