Potassium thiocyanate acts as an efficient sulfur surrogate in C–S cross-coupling reactions mediated by recyclable copper oxide nanoparticles under ligand free conditions. This protocol avoids foul smelling thiols, for the synthesis of a variety of symmetrical diaryl sulfides, via the cross-coupling of different aryl halides with potassium thiocyanate, affording corresponding products in moderate to excellent yields.

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

We show that the energetically-favorable coordination of aldehydes and ketones – but not esters – to nickel(0) during Suzuki-Miyaura reactions can lead either to exquisite selectivity and enhanced reactivity, or to the inhibition<br>of the reaction. Aryl halides where the C-X bond is connected to the same π-system as an aldehyde or ketone functional<br>group undergo unexpectedly rapid oxidative addition, and are selectively cross-coupled during inter- and intramolecular<br>competition reactions. When aldehydes and ketones are present elsewhere, such as in the form of exogenous additives,<br>the cross-coupling reaction is inhibited depending on how strongly the pendant carbonyl group can coordinate to nickel(0). This work advances our understanding of how common functional groups interact with nickel(0) catalysts, and presents synthetic chemists with a tool that can be used to achieve site-selectivity in functionalized molecules. <br>
