Abstract: The hydroaminomethylation of 1-decene in the RhCl(CO)(TPPTS)2-TPPTS[P(m-C6H4SO3Na)3]/TPPDS[C6H5P(m-C6H4SO3Na)2]- CTAB aqueous/organic biphasic system was studied under different conditions of molar ratios of TPPTS to TPPDS, reaction pressures, and concentrations and structures of cationic surfactants. The synergistic effect of TPPTS and TPPDS on the regioselectivity was observed. The results showed that the ratio of linear/branched amine rose from 8.2 (without TPPDS) to 21.0 ([TPPTS]/[TPPDS] = 4:1). The structure of cationic surfactants exhibited an important influence on the regioselectivity. The ratio of linear/branched amine decreased when using dou-ble-chain cationic surfactants instead of single-chain cationic surfactants. The cationic surfactant that could form compact aggregate favored the formation of linear amine.
