The silicon-based cross-coupling reaction has attracted much attention over recent decades because there are many advantages in using organosilicon compounds. However, the use of reagents with a triorganosilyl group as a key function remains to be established. This account summarizes our recent progress in cross-coupling chemistry with such silyl reagents.1 Introduction2 Preparation of HOMSi Reagents from Aryl Bromides and Disilanes3 HOMSi Reagents from Heteroaromatics and Hydrosilanes4 Cross-Coupling Polymerization with HOMSi Reagents5 Cross-Coupling with Aryl(triethyl)silanes6 Amination of Aryl Halides with N-TMS-Amines7 Conclusion and Perspective

Manganese Species

Various substituted bis-(aryl)manganese species were prepared from aryl bromides by one-pot insertion of magnesium turnings in the presence of LiCl and in situ trans-metalation with MnCl2 in THF at −5 °C within 2 h. These bis-(aryl)manganese reagents undergo smooth iron-catalyzed cross-couplings using 10 mol% Fe(acac)3 with various functionalized alkenyl iodides and bromides in 1 h at 25 °C. The aryl-alkenyl cross-coupling reaction mechanism was thoroughly investigated through paramagnetic 1H-NMR, which identified the key role of tris-coordinated ate-iron(II) species in the catalytic process.
