Following upon the synthesis of new proligands Me2NCH2XCH2NMe2
(X = O or NMe), we have now prepared quarternised derivatives of the related phosphorus compounds, R2NCH2XCH2NR2
(R = Me or Et, X = PPh). The ethyl compound can act as a phosphorus donor even when the nitrogen atoms are protonated, and we have characterised fully [NiBr4PhP(CH2NHEt2)2}2][NiBr4] as well as a polymeric adduct of NiBr2 and thf, [Ni3Br6(thf)5}n].
继合成了新的原载体 Me2NCH2XCH2NMe2(X = O 或 NMe)之后,我们现在又制备了相关
磷化合物 R2NCH2XCH2NR2(R = Me 或 Et,X = PPh)的四分化衍
生物。即使氮原子质子化,乙基化合物也可以作为
磷的供体,我们已经完全表征了 [NiBr4PhP(CH2NHEt2)2}2][NiBr4] 以及 NiBr2 和 thf 的聚合物加合物 [Ni3Br6(thf)5}n]。
