Polypnictogen-transfer reagents

多砷和多磷化合物代表了目前人们感兴趣的重要化合物类别，特别是因为它们通过等球和对角线关系与各自的有机化合物表现出强烈的结构关系，但在反应性方面表明了相当大的差异。由于这类物质通常是用黄砷或白磷制备的，在许多合成实验室中，由于其毒性和对氧气和光线的极端敏感性，只能有限制地处理，因此有必要为En单位（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试剂，该转移试剂可以用简单的方法制备。利用这些富氮原料，可以获得过渡金属的多砷和多磷衍生物以及主要族元素，从而以前所未有的富元素杂芳香化合物、杂原子笼化合物和高分子化合物的形式存在。As4和P4转移试剂可以在室温或更低的温度下制备，它们的使用将为含有迄今未知的En结构基序的新亚稳类化合物打开大门。除了生成新的主族元素和过渡金属化合物外，还针对砷和磷的新改性进行了合成。

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.
