During the hydrogenation of the Δ3(3a)-4-hydrindenones or on Pd or Ni, we observe a shift of the double bond to Δ3a(7a)-4-hydrindenones and . The absolute configuration established for ketones and shows that the reaction is a suprafacial process. By deuteriation experiments, we observe that the reaction is irreversible and occurs with a molecular hydrogen exchange.
在Δ3 (3a) -4-氢化
茚酮或Pd或Ni上的氢化过程中,我们观察到双键向Δ3a (7a) -4-氢化
茚酮和转移。建立了酮的绝对构型,表明该反应是超表面过程。通过
氘化实验,我们观察到该反应是不可逆的,并且与分子氢交换发生。
