•Immobilization of water-soluble Rh-m-TPPTC and Rh-TPPTS complexes onto a layered double hydroxide Zn-Al (LDH).•Catalysts characterizations: XRD patterns and ICP-AES analyses.•Rh-catalyzed hydroarylation of alkynes in biphasic aqueous medium.•Recycling of the catalyst.
Rh-m-TPPTC complex was successful immobilized onto a hydrotalcite Zn-Al to convert selectively in aqueous media both the symmetric and nonsymmetric alkynes into functionalized alkenes, with boronic acids. The complex preserved its activity after the ionic exchange, leading to excellent results (∼87%) for the symmetric alkynes and also for the non-symmetrical alkynes (up to 99%).
