摘要
The mechanism of Fe- or Ni- catalyzed hydrogenation of 9,10-diphenylanthracene (9,10-DPA) in decalin in the presence of sulfur was investigated. The qualitative and quantitative analyses of reaction products were conducted by GC-MS. The results showed that Fe and Ni mainly catalyzed non-ipso hydrogenation of 9,10-DPA without sulfur, whereas trans-9,10-dihydro-9,10-diphenylanthracene was main product for both iron sulfide- and nickel sulfide-catalyzed reactions, which suggested that hydrogen atoms was primarily transferred to ipso positions and to different sides of anthracene ring in 9,10-DPA. Quite different catalysis between metals and their sulfides should be responsible for the various mechanisms for hydrogen transfer. It is suggested that metals mainly catalyze diatomic hydrogen transfer, whereas their sulfides primarily promote monatomic hydrogen transfer.
