C 60与磺酰胺或磷酰二酰胺的碘价促进的高价分子间胺化反应提供了两类新型的C 60稠合的环状磺酰胺或磷酰二酰胺衍生物。可以有效地控制C 60和磺酰胺之间的反应,以分别在PhIO / I 2或PhI(OAc)2 / I 2条件下选择性地合成电子化产物或氮杂富勒烯类化合物。而且,磷酰基二酰胺首先被用作烯化中的胺源。
A hypervalent iodine-promoted intermolecular diamination reactions of C60 with sulfamides or phosphoryl diamides affords two classes of novel C60-fused cyclic sulfamide or phosphoryl diamide derivatives. The reaction between C60 and sulfamides can be effectively controlled to selectively synthesize diamination products or azafulleroids under PhIO/I2 or PhI(OAc)2/I2 conditions, respectively. Moreover

series of 2-oxo or 2-thioxo1,3-disulfonyl-1,3,2-diazaphospholidines 4was prepared by condensation of phosphonyl dichlorides 2 with bis-N,N'-sulfonylethylenediamines 1 in pyridine. Complete aminolysis or alcoholysis of heterocycles 4 took place with regeneration of sulfonyldiamines 1. These reactions are very sensitive to steric hindrance, and hydrolysis is generally favoured over aminolysis. The results
