Trialkylphosphonium Oxoborate as C(sp3)−H Oxyanion Hole Catalyst for Diels‐Alder Reaction

We have developed a catalytic protocol for Diels‐Alder reaction using trialkylphosphonium oxoborates as oxyanion hole catalysts. The reaction can be operated under ambient conditions. Dienes could easily polymerize under acidic condition. Nonetheless, these acid‐sensitive substrates are compatible w...

Description
Summary:We have developed a catalytic protocol for Diels‐Alder reaction using trialkylphosphonium oxoborates as oxyanion hole catalysts. The reaction can be operated under ambient conditions. Dienes could easily polymerize under acidic condition. Nonetheless, these acid‐sensitive substrates are compatible with the catalytic protocol and the reaction scope covers a wide range of substrates.
