Cobaloxime (Co(dmgBF2)2·2H2O), an inexpensive first-row transition-metal complex, catalyzed hydration of terminal alkynes gave the corresponding methyl ketones in good to excellent yields under neutral conditions (additional protic acids and silver salts are not required). A wide range of functional groups, such as allyl ether, benzyl ethers, carboxylic esters, imides, amides, nitro, and halogens,
钴肟(Co(dmgBF 2)2 ·2H 2 O),一种廉价的第一行过渡
金属络合物,在末端
炔烃的催化
水合下,在中性条件下以良好或优异的收率得到了相应的甲基酮(另外的质子酸和
银盐是不需要)。耐受各种官能团,例如
烯丙基醚,苄基醚,
羧酸酯,
酰亚胺,酰胺,硝基和卤素。温和的反应条件以及廉价的特征和催化剂的容易获得性很好地解决了
炔烃水合领域中的当前挑战。
