molecules bearing single, double, and triple bonds. Addition of chalcogens (O2, S8, Sex and Tex) led to the formation of dichalcogen‐bridged P2N2 heterocycles, except from the reaction with molecular oxygen, which gave a P2N2 ring featuring a dicoordinated PIII and a four‐coordinated PV center. In formal [2πe+2πe] addition reactions, small unsaturated compounds such as ethylene, acetylene, acetone,
双自由基[P(μ-NTer)] 2的反应活性被用来激活带有单键,双键和三键的小分子。硫族元素(O 2,S 8,Se x和Te x)的添加导致了二氢桥联的P 2 N 2杂环的形成,除了与分子氧的反应外,它还形成了一个P 2 N 2配位的P 2 N 2环。III和四坐标P V中央。在正式[2πe+2πe]加成反应,如乙烯,乙炔,丙酮,乙腈,二苯乙炔,苯基碳二和双(三甲基硅烷基)sulfurdiimide小的不饱和化合物被容易地添加到P 2 Ñ 2的biradicaloid的杂环[P(μ ‐NTer)] 2,产生新的杂原子笼状化合物。详细研究了双自由基[P(μ-NTer)] 2的合成,反应和键合,以及所有加成产物的合成,性质和结构特征。
