Sterically bulky N,N¢-disubstituted cyclic thiourea ligand L1 has been demonstrated as an efficient ligand in palladium-catalyzed oxidation of alcohols using molecular oxygen as an oxidant. This new catalyst system has been applied to a wide variety of substrates such as benzylic alcohols, aliphatic secondary alcohols and allylic alcohols, producing the corresponding carbonyl compounds in good to excellent yields.
立体庞大的N,N¢-二取代环硫脲配体L1已被证明在以分子氧作为氧化剂的钯催化醇氧化反应中是一种高效的配体。该新催化剂系统已应用于多种底物,如苯甲醇、脂肪族二级醇和烯丙醇,产生相应的羰基化合物,其收率良好至优异。
