Synthesis of nanostructured materials by a new solid state pyrolysis organometallic polymer method (2005)In this study, the preparation of nanostructured particles of metal/metal oxides by using a pyrolysis of organometallic polyphosphazenes having the metal anchored to the polymeric chain is described. The elaboration process ...
-
(2016)A p-tertbutylcalix[4]arene derivative was synthesized from a reaction of the diisothiocyanate p-tertbutylcalix[4]arene, obtaining crystals that were then characterized by mass spectroscopy, Raman spectroscopy, and ...
-
(2003)The preparation and spectroscopic properties of new dipyrido[3,2-a:2′,3′-c]phenazine ruthenium complexes are described. The complexes show high catalytic activity in the water gas shift reaction in a basic medium under ...
-
(2013)A novel methodology for the synthesis of S- and N-functionalized dithiocarbamates starting from cyclic sulfates, amines and carbon disulfide by using different protocols, including microwave assistance and a multicomponent ...

Synthesis, characterization and crystal structure of [Ru(tppz)(4,4′-(CH3)2bpy)Cl](PF6), (tppz = ... (Elsevier Ltd, 1996)The synthesis and characterization of the complex [Ru(tppz)(4,4′-(CH3)2bpy) Cl]+ , where tppz = 2,3,5,6-tetrakis(2-pyridyl)pyrazine, is reported. The ion was obtained in a one pot synthesis by reduction of Ru(4,4′-(CH3)2bpy)Cl4 ...

(Elsevier, 2015)In this work we report the preparation of six new donor–metal–acceptor (D–M–A) type complexes of ruthenium(II) with the highly absorbing ‘‘chromophoric’’ ligand 4,40-bis(2-(4-methoxyphenyl)styryl)- 2,20-bipyridine, ...
-
(Elsevier, 2017)Nitrogen compounds are widely investigated due to their pharmacological properties such as antihypertensive, antinociceptive, antibacterial, antifungal, analgesic, anticancer and inhibition activities and lately even as ...
-
(2001)A series of S-nitrosothiol compounds, structurally related to the NO-donor S-nitroso-N-acetyl-D,L-penicillamine (SNAP) that contain amidin groups were synthesised by S-nitrosation of the corresponding thiols and characterised. ...
-
(Elsevier, 2004)Layered compounds are nanostructured, intrinsically anisotropic materials which often undergo intercalation reactions producing host– guest complexes. In this work examples from the molybdenum disulfide chemistry are used ...
-
(Elsevier, 2020)During the last decade, the one drug-one target strategy has resulted to be inefficient in facing diseases with complex ethiology like Alzheimer's disease and many others. In this context, the multitarget paradigm has ...
