Latest News: Reactions of Group 4 Bis(trimethylsilyl)acetylene Metallocene Complexes and Applications of the Obtained Products
Recently published reactions of group 4 metallocene bis(trimethylsilyl)acetylene (btmsa) complexes from the last two years are reviewed. Complexes like Cp’(2)Ti(η(2)‐Me(3)SiC(2)SiMe(3)) and Cp(2)Zr(py)(η(2)‐Me(3)SiC(2)SiMe(3)) with Cp’ as Cp (cyclopentadienyl) and Cp* (pentamethylcyclopentadienyl) h...

description | Recently published reactions of group 4 metallocene bis(trimethylsilyl)acetylene (btmsa) complexes from the last two years are reviewed. Complexes like Cp’(2)Ti(η(2)‐Me(3)SiC(2)SiMe(3)) and Cp(2)Zr(py)(η(2)‐Me(3)SiC(2)SiMe(3)) with Cp’ as Cp (cyclopentadienyl) and Cp* (pentamethylcyclopentadienyl) have been considered (py=pyridine). These complexes can liberate a reactive low‐valent titanium or zirconium center by dissociation of the ligands and act as ‘‘masked’’ M(II) complexes (M=Ti, Zr). They represent excellent sources for the clean generation of the reactive coordinatively and electronically unsaturated complex fragments [Cp’(2)M]. This is the reason why they were used for many synthetic and catalytic reactions during the last years. As an update to several review articles on this topic, this contribution provides an update with recent examples of preparative organometallic and organic chemistry of these complexes, acting as reagents for a wide range of coordinating and coupling reactions. In addition, applications and investigations concerning reaction products derived from this chemistry are mentioned, too. |
