A water-stable palladium complex supported onto nanomagnetite particles was prepared and characterized. The nanocatalyst showed excellent reusability and activity in aqueous phase processes including the C(sp2)-C(sp2) cross coupling reactions. The advantages of the protocol are its generality, high yields, short reaction time, a cleaner reaction profile, and simplicity.

The Ni-catalysed cross-coupling of aryl ethers is a powerful method to forge new C?C and C?heteroatom bonds. However, the inert C(sp2)?O bond means that a canonical mechanism that relies on the oxidative addition of the aryl ether to a Ni0 centre is thermodynamically and kinetically unfavourable, which suggests that alternative mechanisms may be involved. Here, we provide spectroscopic and structural insights into the anionic pathway, which relies on the formation of electron-rich hetero-bimetallic nickelates by adding organometallic nucleophiles to a Ni0 centre. Assessing the rich co-complexation chemistry between Ni(COD)2 and PhLi has led to the structures and solution-state chemistry of a diverse family of catalytically competent lithium nickelates being unveiled. In addition, we demonstrate dramatic solvent and donor effects, which suggest that the cooperative activation of the aryl ether substrate by Ni0-ate complexes plays a key role in the catalytic cycle.

Paragraph 0017; 0088-0091, (2021/03/13)
An object is to establish a technology with which an organic magnesium compound can be easily and efficiently synthesized at a low cost with few steps that do not involve a complex chemical method. A method for synthesizing an organic magnesium compound includes, in a reaction solvent, reacting an organic halide represented by General Formula I (Ra—Xa) with a dispersion product obtained by dispersing sodium in a dispersion solvent to obtain an organic sodium compound represented by General Formula II (Ra—Na), and reacting the obtained organic sodium compound with a magnesium halide represented by General Formula III (Mg—(Xb)2) to obtain an organic magnesium compound represented by General Formula IV (Ra—Mg—Xb).
