Regio- and stereoselective nucleophilic attack of cyanide (from NBu4CN) to cationic diiron vinyliminium compounds [Fe2Cp2(CO)(mu-CO){mu-eta(1):eta(3)-C-(R')C(R '')-CNMe2}]CF3SO3 ([1a-f]CF3SO3) affords the nitrile-aminoallylidene derivatives 2a-f in good to ...
Neutral piano-stool complexes of the general formula [(eta(5)-C5Me5)Rh(L-OR)] (R = Me, 1; R = Et, 2; R = Pe(i), 3) have been prepared in alcohols (methanol, 1; ethanol, 2; isopropanol, 3) from the Schiff-base 5-methyl-4-{(pyridin-2-ylmethylene)amino}-4H-1, ...
The first examples of (arene)Os(II) curcuminoid derivatives have been prepared and characterized. The neutral complexes [(p-cym)Os(curc)Cl] (1) and [( p-cym)Os(bdcurc)Cl] ( 2), together with the cationic derivatives [( p-cym)Os(curc)(PTA)][SO3CF3] (3) and ...
Curcuminoids and their complexes continue to attract attention in medicinal chemistry, but little attention has been given to their metabolic derivatives. Here, the first examples of (arene)Ru(II) complexes with curcuminoid metabolites, tetrahydrocurcumin ...
A series of Ga(Q(n))(3) coordination compounds have been synthesized, where HQ(n) is 1-phenyl-3-methyl-4-RC(=O)-pyrazolo-5-one. The complexes have been characterized through analytical data, NMR and IR spectroscopy, ESI mass spectrometry, elemental analysi ...
