Polypnictogen-transfer reagents

多砷和多磷化合物是当前研究的重要化合物，特别是因为它们通过等规线和对角关系与各自的有机化合物显示出很强的结构关系，但在反应活性方面表现出相当大的差异。由于这类物质通常是用黄砷或白磷进行制备合成的，而在许多合成实验室中，只能根据它们的毒性和对氧和光的极端敏感性来严格处理这些物质，因此有必要为EN单元(E=P，As)开发合适的储存和转移试剂。该项目的目标是合成具有富元素单元的新型转移剂，该转移剂可以以简单的方式进行制备。利用这些富烯原料，可以获得过渡金属的多砷和多磷衍生物以及主族元素，从而以前所未有的富含元素的杂芳烃、杂原子笼状化合物和聚合物的形式存在。AS4和P4转移试剂的使用，可以在常温和更低的温度下制备使用，将打开获得含有迄今未知的EN结构基序的新的亚稳定类化合物的途径。除了生成新的主族元素和过渡金属化合物外，还致力于合成新的砷磷改性化合物。

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.
