Titanium dioxide‐supported silver nanoparticles were utilized as a highly efficient catalyst for the addition of terminal alkynes to aldehydes to prepare propargylic alcohols with the promotion by triphenylphosphine. Both a significant support effect and a ligand effect were observed in the catalytic reaction. With this protocol, various propargylic alcohol derivatives were synthesized from aldehydes
二氧化钛负载的银纳米粒子被用作高效催化剂,用于将末端炔烃添加到醛中,以制备由三苯基膦促进的炔丙醇。在催化反应中观察到显着的支持作用和配体作用。通过该协议,可以从醛和末端炔烃以良好至极好的收率合成各种炔丙醇衍生物。此外,该催化剂可以有效地回收和再利用而不会明显降低催化活性。
