corresponding W(CO)5 complex and the O and S derivatives for added stability as was demonstrated for aminophosphine (11a). From this building block, very sensitive product mixtures containing tetraphospha[4]pericyclynes (16) were obtained. In addition, the amino-substituent of phosphines (11) could be removed upon treatment with HCl to give chlorophosphine (18) from which novel trisethynylphosphines
的反应我-Pr 2 NPCL 2与炔格氏试剂导致的新炔属取代的磷积木的形成。这些结构单元可以通过形成相应的W(CO)5配合物以及O和S衍生物来加以保护,以提高稳定性,如氨基膦(11a)所示。从该结构单元中,获得了非常敏感的含有四磷[4]环炔烃的产物混合物(16)。另外,在用HCl处理后,可以除去膦的氨基取代基(11),得到氯膦(18),从中可以得到新的三乙炔基膦(19)。)带有不同的取代炔烃,这些炔烃可以用作新型三维磷酸-炔属骨架的构建基块,例如(二)乙炔基扩展的磷酸氢二钠8和25,根据DFT计算,它们具有更高程度的环状电子离域化与它们的碳类似物相比,减少了HOMO-LUMO的缺口。
