Cyclic phosphazenes with different substituents were synthesised and investigated by liquid chromatography (LC) and electrospray ionisation mass spectrometry (ESI-MS). Hexachlorocyclotriphosphazene was functionalised with aliphatic substituents as alcohols and amines, leading to product mixtures, which were subsequently analysed. In contrast to classical methods of structural analysis such as nuclear
合成了具有不同取代基的环状磷腈,并通过液相色谱(LC)和电喷雾电离质谱(ESI-MS)进行了研究。六氯环三磷腈被脂族取代基(如醇和胺)官能化,生成了产物混合物,随后对其进行了分析。与仅限于纯化合物的经典结构分析方法(如核磁共振波谱学或X射线晶体学)相比,这些复杂的混合物可以通过LC / ESI-MS进行分析。可以从副产物中分离出主要产物,此外,通过精确的质量测量可以明确地识别未知混合物的所有成分。对于所有具有不同侧链比的化合物,
