Abstract

Aldehydes P 0170Aqueous-Biphasic Hydroformylation of Alkenes Promoted by "Weak" Surfactants. -The aqueous-biphasic hydroformylation of higher alkenes (II) and (VI) catalyzed by Rh/TPPTS is carried out in the presence of imidazolium, pyridinium and triethylammonium salts. High reaction rates are achieved with (I) provided that their alkyl chain is >C8. Furthermore, fast and complete phase separation and good retention of the metal in aqueous phase is achieved with the octyl side chain. The nature of the anion shows a moderate influence on the reaction. -(DESSET, S. L.; READER, S. W.; COLE-HAMILTON*, D. J.; Green Chem. 11 (2009) 5, 630-637; EaStChem, Sch. Chem., Univ.
