Immobilized palladium nanoparticles on potassium zirconium phosphate as an efficient recoverable heterogeneous catalyst for a clean Heck reaction in flow

Palladium nanoparticles on layered potassium α-zirconium phosphate (PdNP/α-ZrPK) with high palladium loading (10.6 wt%) have been prepared and used as catalyst in low amount (0.1 mol% of Pd) in the Heck reaction of methyl acrylate and styrene with a series of aryl iodides in CH3CN/H2O azeotrope as a green medium. The procedure has been optimized under flow conditions obtaining an extremely low waste production (E-factor) and allowing to isolate the final product with very low residual palladium content without any purification step.

An efficient one-pot approach to phenanthrene derivatives using a catalyzed tandem Ullmann-pinacol coupling reaction

In the presence of catalyst (Ph3P)2NiCl2 and reductant Zn, the Ullmann reactions of ortho-halo aryl aldehydes generate biaryl-dialdehydes and zinc halides. Subsequently, ZnX2 can catalyze the intramolecular pinacol coupling reaction of biaryl-dialdehydes to form 9,10-dihydrophenanthrene-9,10-diols. One-pot synthesis of 9-phenanthrols can be achieved using this strategy.

THE COUPLING OF ORGANIC GROUPS BY THE ELECTROCHEMICAL REDUCTION OF ORGANIC HALIDES: CATALYSIS BY 2,2'-BIPYRIDINENICKEL COMPLEXES

The electrochemical reduction of a dilute solution of NiX2bipy (bipy = 2,2'-bipyridine) in N-methylpyrrolidone gives the corresponding Ni0 complex, which undergoes oxidative addition with an excess of an organic halide RX to form RNiX.Decomposition of RNiX gives the dimer R2 in good yield and nickel(II).The nickel(0) species is regenerated to give an electrocatalytic process.The possible mechanism of these reactions is discussed briefly.
