  Reactivity of [M(CO)4(nbd)] (M = Cr or Mo; nbd = norbornadiene) toward (Ph2PN)C(Ph)[N(SiMe3)2] and C6H4{C[N(SiMe3)2 ](NPPh2)}2-1,4

  摘要：

  (Ph₂PN)C(Ph)[N(SiMe₃)₂]与1当量的[M(CO)₄(nbd)] (M = Cr或Mo, nbd = 脱氢樹脂)在醚中反应，产生了cis-[M(CO)₄{(Me₃SiN)C(Ph)(NHPPh₂)}] (M = Cr 1或Mo 2)，产率良好。C₆H₄{C(NPPh₂)[N(SiMe₃)₂]}₂-1,4与2当量的[M(CO)₄(nbd)] (M = Cr或Mo)在四氫呋喃中反应，生成了对称二聚体cis-[{M(CO)₄}{(Ph₂PNH)(Me₃SiN)CC₆H₄C(NSiMe₃)(NHPPh₂)}] (M = Cr 3或Mo 4)，产率中等。然而，在醚中，此反应 (M = Mo) 产生了不对称的cis-[(OC)₄Mo{(Ph₂PNH)(Me₃SiN)CC₆H₄C[N(SiMe₃)₂](NPPh₂)}Mo(CO)₅] 5，产率中等。化合物1-5已通过分析和光谱方法完全表征，3和5的结构已通过X射线晶体学确定。提出了一种1,3-硅位移机制来解释产物的形成。双齿亚氨膦配体的NH质子在常温下与D₂O发生容易的氘交换。

  The interaction of (Ph 2 PN)C(Ph)[N(SiMe 3 ) 2 ] with 1 equivalent of [M(CO) 4 (nbd)] (M = Cr or Mo, nbd = norbornadiene) in diethyl ether gave cis-[M(CO) 4 (Me 3 SiN)C(Ph)(NHPPh 2 }] (M = Cr 1 or Mo 2) in good yield. The interaction of C 6 H 4 C(NPPh 2 )[N(SiMe 3 ) 2 ]} 2 -1,4 with 2 equivalents of [M(CO) 4 (nbd)] (M = Cr or Mo) in tetrahydrofuran gave the symmetric dimer cis-[M(CO) 4 }(Ph 2 PNH)(Me 3 SiN)CC 6 H 4 C(NSiMe 3 )(NHPPh 2 )}] (M = Cr 3 or Mo 4) in moderate yield. However, in diethyl ether, this reaction (M = Mo) gave the unsymmetric cis-[(OC) 4 Mo(Ph 2 PNH)(Me 3 SiN)CC 6 H 4 C[N(SiMe 3 ) 2 ](NPPh 2 )}Mo(CO) 5 ] 5 in moderate yield. Compounds 1–5 have been fully characterized by analytical and spectroscopic methods and the structures of 3 and 5 have been established by X-ray crystallography. A 1,3-silyl shift mechanism has been proposed for the formation of the products. The NH proton of the bidentate iminophosphine ligand undergoes facile deuterium exchange with D 2 O at ambient temperature.
