  Formation of platinum allyl and propargyl complexes from protonation of platinum enyne and diyne complexes

  摘要：

  Protonation of (Ph3P)(2)Pt[eta(2)-HC drop CC(CH3)=CH2] (2a) with excess HBF4 . Et2O produced the pi-allyl complex (Ph3P)(2)Pt[eta(3)- H2C=CC(CH3)=CH2]+BF4-(3a-BF4) instead of a pi-propargyl complex. Reaction of excess CF3CO2H with 2a initially produced the analogous pi-allyl complex 3a-CF3CO2 which then added CF3CO2H across the vinylidene unit of 3a-CF3CO2 to give the pi-allyl complex (Ph3P)(2)Pt[eta(3)-CH3C(CF3CO2) C(CH3)CH2]+CF3CO2-(5a). Protonation of the platinum diyne complex [(p-CH3-C6H4)(3)P](2)Pt(eta(2)- CH3C drop CC drop CCH3) (7b) with HBF4Et2O at -73 degrees C initially produced the platinum hydride complex trans-[(p-CH3-C6H4)(3)P](2)- PtH(eta(2)-CH3C drop CC drop CCH3)+BF4-(9), which rearranged to the platinum pi-propargyl complex [(p-CH3-C6H4)(3)P](2)Pt[eta(3)-(CH3CH=)-CC drop CCH3]+BF4-(11) at -28 degrees C.

• Oxidative addition - reductive elimination sequences in the photochemistry of some bis(phosphine)platinum complexes

  P(p-C6H4CH3)3 complexes in halocarbon solvents (CH2Cl2, CH2Br2) gives C2H4 and the coordinatively unsaturated species [L2Pt]. Photolysis of platinum metallacycles [L2Pt(CH2)4] (L = PPh3, P(n-Bu)3) generates alkanes, alkenes and [L2Pt]. The [L2Pt] centers are very reactive, and under prolonged photolysis undergo oxidative addition of CH2Cl2 forming the trans-[L2Pt(CH2Cl)Cl] complexes. Under appropriately

  [L 2 Pt（C 2 H 4）]（L = PPh 3，P（p -C 6 H 4 CH 3）3络合物在卤代烃溶剂（CH 2 Cl 2，CH 2 Br 2）中的光解得到C 2 H 4和配位不饱和物质[L 2 Pt]。铂金属环[L 2 Pt（CH 2）4 ]（L = PPh 3，P（n-Bu）3）的光解生成烷烃，烯烃和[L 2[Pt]。[L 2 Pt]中心非常活泼，在长时间的光解过程中会经历CH 2 Cl 2的氧化加成反应，形成反式-[L 2 Pt（CH 2 Cl）Cl]络合物。在适当控制的条件下，在双分子C 2 H 4消除发生之前，反式配合物异构化为顺式，最终形成[L 2 PtCl 2 ]。基于自旋俘获实验，量子产率值以及对自由基抑制剂和溶剂的敏感性，讨论了氧化加-还原消除机理。

  Reaction of [Pt(C2H4)(PR3)2](R = Ph or C6H4Me-4) with moderately bulky phosphines at low temperatures did not give the expected tris- or tetrakis-phosphine complexes. Instead, mixed-phosphine complexes of the type [Pt(C2H4)(PR3)(PR′3)](R′= C6H11, C6H4OMe-4, C6H4OMe-2, C6H4Me-4 or CH2Ph) were formed. With less bulky phosphines, chelating diphosphines or phosphites, mixed tetrakis complexes, many of them prone to disproportionation, were formed. The complexes were characterised by 31P and 195Pt NMR spectroscopy in solution.

  在低温下，[Pt(C2H4)(PR3)2](R = Ph或C6H4Me-4)与中等体积的膦反应并未生成预期的三膦或四膦配合物。相反，形成了类型为[Pt( )(PR3)(PR′3)]的混合膦配合物（R′= C6H11, C6H4OMe-4, C6H4OMe-2, C6H4Me-4或CH2Ph）。与体积较小的膦反应时，形成了配位的二膦或磷酸酯的混合四膦配合物，其中许多配合物易于发生不均匀化。该配合物通过31P和195Pt NMR光谱在溶液中进行了表征。
