Several aminated Fullerene derivatives were synthesized by the reaction of C〓 with phenylamine, diphenylamine and triethylamine etc., the phenomena of fragmentation and aggregation of the aminated Fullerene derivatives in UV laser desorption ionization mass spectrometer was observed, a few nitrogenous poly-Fullerene ions, such as C〓NH, C〓N〓H〓, C〓N〓H〓, C〓N〓H〓, C〓N〓H〓 etc.

对C〓富勒烯与苯胺、二苯胺、三乙胺等形成的加合物在紫外激光解吸电离作用下可以发生不同寻常的裂解和聚合现象进行了研究，认为其形成机理为：上述加合物在紫外激光解吸电离作用下，发生裂解产生C〓NH、C〓N及C〓等离子，然后它们之间发生聚合，形成如：C〓NH、C〓N〓H〓、C〓N〓H〓、C〓N〓H〓、C〓N〓H〓等含氮原子的聚富勒烯离子。

And through analyzing the stable configuration of photoactive compounds, the existence of triethylamine salt of diesterified product was thought to be the main factor that affects the solubility.

通过分析，确认二酯化产物三乙胺盐是影响感光剂溶解度的主要原因。

With 4 Xiu Shuang phenol - A and solid smooth air is raw material, dissolve it in 1 in, 2- 2 chlorine ethane solvents, slow drop adds 3 Yi Ans to carry out solution get together , with 3 Xiu benzene phenol does end dose, thick product sinks by industrial alcohol Xi after, take out to strain , wash is dry , grind white powder form flame retardant assemble carbon sour ester product.

以四溴双酚-A、固体光气为原料，将之溶解在1，2-二氯乙烷溶剂中，缓慢滴加三乙胺进行溶液聚合，以三溴苯酚做封端剂，粗产品经工业酒精沉析后，抽滤，洗涤，干燥，研磨得白色粉末状阻燃聚碳酸酯产品。

A base-catalyzed novel olefination methodology based on elimination of p-toluenesulfonamide:Treatment of diethyl cyanomethylphosphonate with catalytic amount of basegave the corresponding phosphoryl-stabilized carbanion, which added to the carbon-nitrogen double bond of N-tosyl imines.
