were reached. A supported version of 1 was realized by reaction of RhCl( NHC )( COD ) with PS - DVB –CH2–O–CO–CF2–CF2–CF2–COOAg ( PS - DVB = poly(styrene- co -divinylbenzene) to yield PS - DVB –CH2–O–CO–CF2–CF2–CF2–COORh( NHC )( COD ). This supported version of 1 exhibited at least comparable, in some cases increased reactivity compared to 1 and allowed the rapid removal of the catalyst from the reaction
<i>N</i>-heterocyclic carbene platinum complexes functionalized with a polyether chain and silyl group: Synthesis and application as a catalyst for hydrosilylation
GRAPHICAL ABSTRACT ABSTRACT The synthesis and characterization of new N-heterocycliccarbeneplatinum(II) complexes functionalized with a polyether chain and silyl group are described. In addition, their application towards the catalytic hydrosilylation of unsaturated carbon–carbon bonds, including alkenes, alkynes, vinyl ether, and unsaturated esters, is reported. These new complexes exhibit both

Highly β(<i>Z</i>)-Selective Hydrosilylation of Terminal Alkynes Catalyzed by Thiolate-Bridged Dirhodium Complexes
A series of novel monothiolate-bridged dirhodium complexes, [Cp*Rh(μ-SR)(μ-Cl)2RhCp*][BF4] Cp* = η5-C5Me5, R = tertiary butyl (tBu), 1a; R = ferrocenyl (Fc), 1b; R = adamantyl (Ad), 1c} were designed and successfully synthesized, which can smoothly facilitate highly regioselective and stereoselective hydrosilylation of terminal alkynes to afford β(Z) vinylsilanes with good functional group compatibility
