Abstract

Well defined layered-double hydroxides (LDH: Mg₃Al-NO₃/CO₃, Mg₃Ga-NO₃/CO₃, Zn₂Al-NO₃/CO₃ and Zn₂Ga-NO₃/CO₃) were prepared using typical procedures starting from Mg(NO₃)₂·6H₂O, Zn(NO₃)₂·6H₂O, Al(NO₃)₃·9H₂O and Ga(NO₃)₃·H₂O. Rh-TPPTS complex was prepared by simple complexation of a Rh precursor [Rh(cod)Cl]₂ and TPPTS (3,3′,3″-phosphanetriyl benzenesulfonic acid) in water. The heterogeneization of the Rh-TPPTS complex was performed by anionic exchange between Rh-complex and LDH supports. The catalysts' structures and the chemical composition were confirmed by chemical analysis, XRD patterns, XP, FTIR and DRIFT spectroscopy. LDH-substituted Rh-TPPTS heterogeneous catalysts showed good catalytic activity in the 1,4-addition of arylboronic acid to 2-cyclohexen-1-one.
