Ferrocene P,N-ligands have been extensively studied due to their favorable catalytic properties. This contribution focuses on a pair of new, isomeric ferrocene phosphinoamines, FcNHCH2CH2PPh2 (1) and FcN(Me)CH2PPh2 (2), which were prepared from aminoferrocene, converted to the respective phosphine selenides (1-Se and 2-Se) and further studied as ligands in Pd(II) complexes containing the 2-(dimeth
二茂铁 P,N-
配体由于其有利的催化性能而被广泛研究。这一贡献侧重于一对新的异构
二茂铁膦胺 FcNHCH 2 CH 2 PPh 2 ( 1 ) 和 FcN(Me)CH 2 PPh 2 ( 2 ),它们由
氨基二茂铁制备,转化为相应的膦
硒化物 ( 1- Se和2-Se ) 并作为
配体在含有 2-(
二甲氨基-κ N ) 苯基-κ C 1辅助
配体 (L NC ) 的 Pd(II) 配合物中进一步研究。因此,二聚体前体的裂解 [(L NC)Pd(μ-Cl)] 2与膦胺得到相应的膦络合物 [(L NC )PdCl( 1 -κ P )] ( 5 ) 和 [(L NC )PdCl( 2 -κ P )] ( 6 )反式-P ,N 配置。随后用 AgClO 4从5中去除
氯化物
配体产生阳离子双螯合物 [(L NC )PdCl( 1 -κ 2 P,N )]ClO 4 ( 7 ),而与6的类似反应没有给出明确的产品
