Imidazolium‐Salt‐Functionalized Ionic‐CNT‐Supported RuCarbene/Palladium Nanoparticles for Recyclable Tandem Metathesis/Hydrogenation Reactions in Ionic Liquids

Chemistry – An Asian Journal, 2013
NP and tuck: Two different catalysts, a Ru-carbene complex and palladium nanoparticles, were immobilized onto the same imidazolium-salt-functionalized ionic CNTs. These supported dual-function catalysts showed excellent catalytic activity in tandem metathesis/hydrogenation reactions in an ionic liquid and could be recovered and reused four times. RCM =

Synthesis and reactivity in salt metathesis reactions of trivalent [La(TpMe2)2X] (X=Cl, I) complexes: crystal structures of [La(TpMe2)2Cl] and [La(TpMe2)2(κ2-pzMe2)]

Polyhedron, 2004
Abstract Reaction of LaX3(THF)n (X = Cl, I) with two equiv. of K(TpMe2) gave good yields of the bis-Tp complexes [La(TpMe2)2X] (X = Cl (1); I (3)). However, the formation of 1 and 3 is always accompanied by significant amounts of La(TpMe2)2(κ2-pzMe2) ([pzMe2]− = 3,5-dimethyl-pyrazolato) (2).

Salt Metathesis and Direct Reduction Reactions Leading to Group 3 Metal Complexes with a N,N′-Bis(2,6-diisopropylphenyl)-1,4-diaza-1,3-butadiene Ligand and Their Solid-State Structures

Organometallics, 2010
We successfully prepared and characterized a wide variety of group 3 metal complexes containing a dianionic or monoanionic glyoxal-based N,N′-bis(2,6-diisopropylphenyl)-1,4-diaza-1,3-butadiene (DAD) ligand using a salt metathesis reaction of group 3 metal trichlorides with the dipotassium salt of the DAD ligand or a direct reduction of the DAD ligand ...

Reactions of K₂[Fe(CO)₃(PPh₃)]: Reductive Sb−Sb Coupling with Ph₂SbCl To Form trans‐[Fe(CO)₃(PPh₃)(Sb₂Ph₄)] and Salt Metathesis with Me₃SbCl₂ To Yield trans‐[Fe(CO)₃(PPh₃)(SbMe₃)]

European Journal of Inorganic Chemistry, 2004
AbstractIn contrast to the ferrate K2[Fe(CO)4], the phosphane‐substituted ferrate K2[Fe(CO)3(PPh3)] (1) reacts with the stibane derivative Ph2SbCl by metal‐assisted reductive Sb−Sb coupling to give the distibane complex trans‐[Fe(CO)3(PPh3)(Sb2Ph4)] (3). The distibane ligand in 3 is terminally η1‐coordinated trans to the phosphane ligand.
