Catalysis with water-soluble rhodium complexes, RhCl(CO)(TPPMS)2, [TPPMS = P(C6H5)2(C6H4SO3)] (1),
RhCl(CO)(TPPDS)2, [TPPDS = P(C6H5)(C6H4SO3)2] (2) and RhCl(CO)(TPPTS)2, [TPPTS = P(C6H4SO3)3] (3)
in hydroformylation of 1-hexene, 2-pentene, 2,3-dimethyl-1-butene, cyclohexene and several mixtures of these olefins
have been studied, under moderate reaction conditions (T: 50–150 C; pCO/pH2 = 1; total p: 14–68 bar; Substrate/
Catalyst: 600/1) in biphasic toluene/water media. The catalytic system shows high activity but low selectivity. The
linear and branched oxygenated products obtained are equally useful in naphtha upgrading, as observed in the real
El Palito naphtha tried. The catalysts can be recycled several times without significant activity [email protected]@ula.ve, [email protected]@[email protected]@[email protected]
