AI Article Synopsis
- Two strategies were developed to prevent the deactivation of Frustrated Lewis pairs (FLPs) in the hydrogenation process.
- A stable polymeric Lewis acid (P-BPh) was synthesized, which shows great effectiveness.
- This new catalytic system achieves up to 99% conversion and selectivity in hydrogenating terminal alkynes and can be recycled easily for repeated use.
Article Abstract
Two strategies were reported to prevent the deactivation of Frustrated Lewis pairs (FLPs) in the hydrogenation of terminal alkynes: reducing the Lewis acidity and polymerizing the Lewis acid. A polymeric Lewis acid (P-BPh) with high stability was designed and synthesized. Excellent conversion (up to 99%) and selectivity can be achieved in the hydrogenation of terminal alkynes catalyzed by P-BPh. This catalytic system works quite well for different substrates. In addition, the P-BPh can be easily recycled.
