“…At present, our research is directed toward the synthesis of the sodium salt of sulfonated pyridine [12,13] as a water-soluble ligand with different metallic centers. The principal goal in this work is the application of rhodium biphasic systems to obtain fuels with high oxygenated products proportion, which would contribute to the improvement of the quality and performance of gasoline through a simple and unique process and finding a friendly environment alternative to avoid the use of ethanol as fuel additive [14][15][16][17][18][19].…”

“…The catalytic carbonylation of olefins in naphtha by oxo or Reppe type process [1][2][3][4][5] has been studied as an alternative route to conventional catalytic alkylation and hydrogenation processes [6][7][8]. Olefins are desirable for their octane value but are unwanted because they lead to deposits and gum formation and increased emissions of ozone forming hydrocarbons and toxic compounds [9].…”

“…Therefore, there is a need to explore other oxygenated additives more environmentally benign. An alternative to this approach can be the in situ transformation of the olefins present in naphtha into oxygenated compounds with high added value, likes esters, aldehydes and acetals, among others, via catalytic carbonylation which it can be carried out in one step avoiding the expensive catalytic hydrogenation [1][2][3][4][5].…”

This work focuses on the use of a gem-dithiolato-bridged rhodium(I) [Rh 2 (μ-S 2 CBn 2 )(cod) 2 ] complex (cod = 1,5-cyclooctadiene, Bn 2 CS 2 2 = 1,3-diphenyl-2,2-dithiolatopropane) dissolved in toluene in the presence of monodentate phosphite P-donor ligand (P(OPh) 3 ) under carbon monoxide/hydrogen (1:1, syngas) atmosphere as an effective catalyst for hydroformylation of some olefins (oxo-reactions). The capability of this system to catalyze the hydroformylation of hex-1-ene, cyclohexene, 2,3-dimethyl-but-1-ene and 2-methyl-pent-2-ene and their quaternary mixture (synthetic naphtha) has been demonstrated. This innovative method to perform the in situ hydroformylation of the olefins present in naphthas to oxygenated products would be a promissory work for a future industrial catalytic process applicable to gasoline improving based on oxo-reactions. An important observation is that variation of CO/H 2 pressure (6.8 34.0 atm), temperature (60 80 ºC), reaction time (2 10 h), rhodium concentration ((1.0 1.8)x10-3 mol/L) affect hydroformylation reaction rates. Optimal conversion to oxygenated products were achieved under [Rh] = 1.8 x10 -2 mol/L, P(CO/H 2 ) = 34 atm (CO/H 2 = 1:1) at 80 ºC for 10 h.

This work describes the carbonylation of hex-1-ene, cyclohexene, 2,3-dimethyl-but-1-ene and 2-methylpent-2-ene, their quaternary mixture and a real Venezuelan naphtha, catalyzed by a rhodium(I) [Rh(cod)(4-picoline) 2 ] (PF 6 ) (cod = 1,5-cyclooctadiene) complex immobilized on poly(4-vinylpiridine) (P(4-VP)) in contact with methanol under carbon monoxide atmosphere. The conversion (%) of olefins to carbonylated products for the individual olefins decreases in the order: hex-1-ene (63) [ cyclohexene (58) [ 2,3-dimethyl-but-1-ene (50) [ 2-methyl-pent-2-ene (31), under the following conditions: 0.5 g of P(4-VP) for [Rh] = 2 wt.% (1 9 10 -4 mol), 10 mL of CH 3 OH, [olefin] = 1 9 10 -2 mol, S/C = 100, P(CO) = 33 atm at 110°C for 24 h. Other products such as H 2 and CO 2 coming from the catalysis of the water-gas shift reaction are observed.
