1-Dodecene hydroformylation catayzed by water soluble rhodium complex [RhCI (CO) (TPPTS) 2] Was studied in the presence of TPPIS [P (m-C6 H4 SO3 Na)3] and CIAB (eetyl-trimethyl ammonium), The influence of reaction parameters was discussed in detail based on micelle effect in biphasic sys-tem. The modification for the microcircunstance of micelle interface Was conducted by the introduction of a catalyst pro-moter TPPDS [PhP (m-C6 H6 SO3 Na) 2] into the reaction solu-tion. A synergistic effect between TPPDS and TPPTS on the regioselectivity of 1-dodecene hydroformylation was observed. The selectivity of linear aldehyde in the products was SO high as 95.7% at the molar ratio of [TPPDS]/[TPPTS]=O.5.

Alumina supported rhodium catalyst using cinchonidine as a stabilizer exhibited excellent performance in the asymmetric hydrogenation of ethyl pyruvate with the addition of quinine. Quinine as a chiral modifier can not only induce the enantioselectivity, but also greatly accelerate the reaction. Under the optimum conditions: 293 K, 7.0 MPa of hydrogen pressure and 4.6×103 mol/L of quinine concentration in THF, TOF of Rh/2(cinchonidine)-c-Al2O3 as catalyst and ee value of (R)-ethyl lactate can achieve 894 h 1 and 71.6% ee, respectively.

1-Dodecene hydroformylation catalyzed by water-soluble rhodium complex, RhCl (CO) (TPPTS) [TPPTS: P (m-C6 H4 SO3 Na)3], in the presence of surfactants and alcoholic solvents was studied. The results indicated that the hydroformylation in biphasic catalytic system occurred in the interface of aqueousrorganic phases. The formation of micelle was not only favorable for the reaction acceleration, but also favorable for the increase of linear aldehyde ratio in products. The key factor of the enhancement of reaction rate was the richness of rhodium catalyst in the interlayer with the static electricity attraction between active rhodium anion species and cationic end of surfactant.
