1,2 -二酮类化合物于乙腈中 ,在氩气保护下 ,用 Ti I4还原成 α-羟基酮 ,6例对称的底物收率 6 7%～ 94% ,不对称的收率低 ,且有异构产物。1,2-二酮用TiI_4还原成α-羟基酮@金卫东
The 1,2 - diketones were reduced to α - hydroxyketones with Ti I4 in acetonitrile under the protection of argon. The yields of 6 symmetrical substrates ranged from 67% to 94%, and the asymmetric yields were low. And there are isomeric products. 1,2-dione with TiI_4 reduced to α-hydroxy ketone @ Jin Weidong
