Man up your magnesium! By employing a MgCl2/Et3N system, aryl diketones can be generated from the Pd-catalyzed carbonylative α-arylation of acetylacetone with aryl bromides (see scheme). The method is ideal for the introduction of carbon isotopes into more complex structures, since only stoichiometric amounts of carbon monoxide are employed. Copyright
The reduction of (1-(4-cyanophenyl)-3-hydroxy-2-buten-1-one-N)pentaamminecobalt(III) by chromium(II)

The reduction of the title compound, by chromium(II) is first order in Cr(II) and obeys the rate law kobsd = k1Ka'/(Ka'+ +>) at 25.0 deg C and I = 1.0 mol L-1 (LiClO4) with k1 = (2.9 +/- 0.1)E4 L mol-1 s-1 and Ka' = 0.86 +/- 0.03 mol L-1.In the rate law, k1 refers to reduction of the 3+ ion above and the Ka' is the acid dissociation constant for the protonated form of 1.The reduction occurs by a remote attack inner-sphere mechanism with complete transfer of the organic ligand to chromium.
