• Synthesis, characterization and catalytic application of some novel PNP-Ni(II) complexes: Regio-selective [2+2+2] cycloaddition reaction of alkyne

  We have also performed alkyne [2+2+2] cycloaddition reaction using Ni(II) complexes and observed high regioselectivity of the products. The observed selectivity is well correlating with the electronic feature of alkynes. The [2+2+2] cycloaddition of electron rich alkynes produced 1,3,5-substituted benzene derivatives as a major product whereas the electron deficient alkynes produced 1,2,4-substituted

  PN（H）P Ph，PN（Me）P iPr和PN（Me）P tBu配体的一些新颖的Ni（II）配合物已通过标准的分析和光谱方法（例如1 H NMR，31 P NMR，元素分析，ESI-MS，紫外可见光谱和单晶X射线晶体学。在三氟甲磺酸银存在下，复合物[PN（H）P Ph NiCl] 2 NiBr 4 （5）在室温下激活二氯甲烷的C-Cl键，得到复合物[PN（H）P Ph NiCl] OTf （6）。我们还使用Ni（II）配合物进行了炔烃[2 + 2 + 2]环加成反应，并观察到了产物的高区域选择性。观察到的选择性与炔烃的电子特征很好地相关。富电子炔烃的[2 + 2 + 2]环加成反应生成1,3,5-取代的苯衍生物作为主要产物，而缺电子炔烃则生成1,2,4-取代的苯衍生物作为主要产物。

  carbyne complexes (≡SiO)xW(≡CH)(Me)y (x = 1, y = 2; x = 2, y = 1) toward alkynes is reported. We found that they are efficient precatalysts for terminal alkyne cyclotrimerization with high TONs. We also demonstrate that this catalyst species is active for alkyne cyclotrimerization without the formation of significant alkyne metathesis products. Additional DFT calculations highlight the importance of the

• Highly regioselective [2+2+2] cycloaddition of terminal alkynes catalyzed by titanium complexes of p-tert-butylthiacalix[4]arene

  Mono- and dinuclear titanium complexes of p-tert-butylthiacalix[4]arene were applied as a catalyst for [2+2+2] cycloaddition of terminal alkynes. They showed high catalytic activity and regioselectivity toward 1,3,5-trisubstituted benzenes over 1,2,4-trisubstituted isomers. The regioselectivity was rationalized in terms of the steric effect of the thiacalixarene skeleton and the coordination of the bridging Sulfur atom to the titanium center. (c) 2005 Elsevier Ltd.
