LA RISONANZA MAGNETICA NUCLEARE PER I FLUIDI NEI MEZZI POROSI APPLICATA AI BENI CULTURALI in memoria di Franco Piacenti

Autor: FANTAZZINI, PAOLA

Allo stato attuale delle ricerche i vantaggi derivanti dalla applicazione ai Beni Culturali [Camaiti, 2010] delle tecniche di Risonanza Magnetica Nucleare (NMR) per i Fluidi nei Mezzi Porosi (MRPM) [Fantazzini, 2005] non hanno più necessità di esse

Influence of an additional gas on the hydroformylation of cyclohexene with Co2(CO)6(PBu3)2

Autor: Piero Frediani, Simona Maggini, Antonella Salvini, Franco Piacenti

Publikováno v: Journal of Molecular Catalysis A: Chemical. 172:127-134

The influence of an additional gas on the hydroformylation of cyclohexene in the presence of Co2(CO)6(PBu3)2 has been tested. The rate of the hydroformylation is reduced by the presence of an appropriate amount of dinitrogen, argon or xenon as additi

Isomerization of olefins by phosphine-substituted ruthenium complexes and influence of an ‘additional gas’ on the reaction rate

Autor: Piero Frediani, Maria Caporali, Andrea Devescovi, Franco Piacenti, Antonella Salvini

Publikováno v: Journal of Organometallic Chemistry. 625:255-267

Phosphine-substituted ruthenium carbonyls have often been used as catalytic precursors in reactions such as the hydrogenation or the hydroformylation of olefins. To collect evidence on the coordination of the olefin as a preliminary step of these rea

Alkene isomerization by non-hydridic phosphine substituted ruthenium carbonyl carboxylates

Autor: Piero Frediani, Antonella Salvini, Franco Piacenti

Publikováno v: Journal of Molecular Catalysis A: Chemical. 159:185-195

The behaviour of phosphine substituted ruthenium carbonyl carboxylates in the presence of hex-1-ene has been followed by IR and NMR spectroscopies. The complex Ru4(CO)8(MeCO2)4(PBu3)2 reacts at room temperature with a large excess of hex-1-ene giving

Publikováno v: Journal of Organometallic Chemistry. 582:218-228

Hydrido ruthenium carbonyl complexes substituted by functionalized phosphines such as H4Ru4(CO)8[P(CH2OCOR)3]4 have been synthesized and tested as catalysts in the hydrogenation of carboxylic acids. These complexes are more active than those reported

Publikováno v: Inorganica Chimica Acta. 272:141-149

The hydrogenolysis of the acetato group by molecular hydrogen in phosphine-substituted ruthenium(I) and (II) carbonyl carboxylates has been reinvestigated in the presence of Na2CO3 at various temperatures. From mononuclear complexes such as Ru(CO)2(M
