to generate (NPP)RuH(CO). X-raycrystallographicstudies confirm that the geometry in the solid state matches the solution spectroscopic data. Subsequent studies of (NPP)RuH(CO) indicate that it reacts with benzaldehyde, benzyl alcohol, and H2 in a cooperative manner to generate a series of hydride carbonyls that have been characterized fully by NMR spectroscopy and X-ray crystallography.
为了生成三齿烯胺二膦配体平台,我们开发了制备t Bu 2 PCH 2 CH 2 P(t Bu)I的程序,该程序涉及低温,戊烷溶剂和添加4当量。的吨丁基锂与cl 2 PCH 2 CH 2的PCl 2或2当量 戊烷在低温下也将t BuLi转化为已知的Cl(t Bu)PCH 2 CH 2 P(t Bu)Cl;一种替代方法涉及反加Cl(t Bu)PCH 2 CH2 P( t Bu)Cl至2当量 在0°C下在戊烷中的t BuLi含量;所有这些方法都能产生少量的t Bu 2 PCH 2 CH 2 P t Bu 2(dtbpe)污染的四膦二聚体( t Bu 2 PCH 2 CH 2 P( t Bu)) 2,具有良好的收率。通过升华分开。随后用I 2或1,2-二碘乙烷将P–P键氧化裂开,从而形成所需的t Bu 2 PCH 2CH 2 P(t Bu)I,当加入1当量时,会经历C–P键形成。环戊叉亚胺的N -
