  Nucleophilic Attack of Amides onto Coordinated Ethylene in Platinum Complexes Supported by a Chelating Pyridyl−Pyrrolide Ligand: Azaplatinacyclobutane and Vinylamine Complexes

  摘要：

  The platinum ethylene complexes (PyPyr)Pt(C2H4)Cl (1) and (PyPyr)Pt(C2H4)OTf (4) (PyPyr = 3,5-diphenyl-2-(2-pyidyl)pyrrolide) were treated with 1 equiv of LiN(SiMe3)(2), (LiNPr2)-Pr-i, and LiNH-(o-xylyl) to produce the platinum complexes (PyPyr)PtH[eta(2)-CH2=CHN(SiMe3)(2)] (5), (PyPyr)Pt[k(2) C,N-((CH2CH2NPr2)-Pr-i)] (6), and (PyPyr)Pt{k(2)C,N-[CH2CH2NH(o-xylyl)]} (7), respectively. X-ray crystallography reveals that 7 adopts a square-planar geometry at the platinum center and the azaplatinacyclobutane ring displays I puckering of the beta-carbon out of planarity by 0.270 angstrom. Thermolysis of 5 and 7 at 60 degrees C for 16 h releases the vinylamines (CH2=CH)N(SiMe3)(2) and (CH2=CH)NH(o-xylyl), respectively. Heating 5 and 7 under 1 atm of H-2 at 60 degrees C releases the ethylamines EtN(SiMe3)(2) and EtNH(o-xyly]), respectively. Addition Of PiPr(3) to 7 produces (PyPyr)Pt((PPr3)-Pr-i)[CH2CH2NH(o-xylyl)] (8) in 95% yield, while additions of I equiv of a Lewis base (L) to I result in displacement of ethylene to give (PyPyr)Pt(L)Cl (L = NEt3 (9), NH2Ph (10), (PPr3)-Pr-i (11)). The amido complex (PyPyr)Pt((PPr3)-Pr-i)[NH(o-xylyl)] (12) results from treatment of 11 with LiNH(o-xylyl), and 12 does not undergo ethylene insertion into the Pt-N bond Linder I atm of C2H4 at 120 degrees C over 3 days. Addition of 1 equiv of LiNH(o-xylyl) to (PyPyr)Pt(SMe2)Cl (2) produces the mu-amido-bridged dimer [(PyPyr)Pt(mu-NH(o-xylxyl))](2) (13), and treatment of 13 with 2 equiv Of (Pr3P)-Pr-i produces 12. These reactivity Studies are consistent with a mechanism for the formation of 5-7 involving nucleophilic attack of ail amide onto coordinated olefin.

  螯合单阴离子氮基配体支持的五配位二氢化硅烷基铂（IV）配合物

  摘要：

  制备含有二齿配体3，5-二苯基-2-（2-吡啶基）吡咯化物（PyPyr）的Pt（IV）的配合物。用HSiEt 3或HSiEtMe 2处理乙烯络合物PyPyrPt（C 2 H 4）Cl（1）以生产Pt（IV）甲硅烷基二氢化物PyPyrPt（H）2 SiEt 3（3）和PyPyrPt（H）2 SiEtMe 2（4）。通过X射线晶体学确定的3的固态结构揭示了通过PyPyr配体之间的π堆积形成的二聚体结构。Lewis碱加3导致配位生成八面体Lewis碱加合物（带有DMAP）或硅烷消除生成方平面的Pt（II）Lewis碱配合物（带有膦）。还发现配合物3是用于炔烃和末端烯烃与HSiEt 3的氢化硅烷化的活性氢化硅烷化催化剂。
