Porous organic polymer supported rhodium as a heterogeneous catalyst for hydroformylation of alkynes to α,β-unsaturated aldehydes

A new porous organic polymer supported rhodium catalyst (Rh/POL-BINAPa&PPh 3 ) has been developed for the hydroformylation of various alkynes to afford the corresponding α,β-unsaturated aldehydes with high chem- and stereoselectivity, excellent catalytic activity and good reusability (10 cycles). The heterogeneous catalyst exhibited more catalytic activity than the comparable homogeneous Rh/BINAPa/PPh 3 system. A novel porous organic polymer supported rhodium catalyst (Rh/POL-BINAPa&PPh 3 ) was developed for the hydroformylation of alkynes to afford α,β-unsaturated aldehydes.
