Polymer-supported tertiaryphosphine (JJ–TPP) as a green and recyclable organocatalyst for α-addition of carbon nucleophiles to α,β-unsaturated compounds

JJ–TPP has been demonstrated as an effective and reusable organocatalyst for α-addition of carbon nucleophiles to α,β-unsaturated compounds under very mild and environmentally friendly conditions. Under the optimized reaction conditions, the desired addition products were obtained as only E isomer with 18–90% isolated yields.
