Abstract Reaction of α- or β -P 4 S 3 I 2 with RNH 2 (R = H, Me, Bu t or Ph) led to new iminobridged cage skeletons in α- or β -P 4 S 3 ( μ -NR), as well as both exo,exo - and endo,exo -isomers of either α- or β -P 4 S 3 (NHR) 2 (except for R = H). Cage compounds P 4 S 2 ( μ -NR) (R = Bu t or Ph) and α -P 4 S 2 ( μ -NR) 2 , with structures analogous to P 4 S 3 and α -P 4 S 4 , respectively, have been
摘要α-或β-P 4 S 3 I 2与RNH 2(R = H,Me,But或Ph)的反应导致在α-或β-P 4 S 3(μ-NR)中形成新的亚氨基桥笼骨架。 ,以及α-或β-P 4 S 3(NHR)2的exo,exo-和endo,exo-异构体(R = H除外)。笼式化合物P 4 S 2(μ-NR)(R = Bu t或Ph)和α-P 4 S 2(μ-NR)2,其结构分别类似于P 4 S 3和α-P 4 S 4 ,已被识别为分解产物。通过对31 P NMR光谱进行全面分析,对新化合物进行了溶液表征。α-P 4 S 3(μ-NR)中的氮桥联构型是平面的。从头开始计算了α-P 4 S 3(μ-NH)的分子几何形状。与相应的与仲胺的反应相反,提出了机制论点以合理化异构体endo,exo-α-P4 S 3(NHR)2的形成,
