  It′s the iodine: The intra‐ and intermolecular title reaction is catalyzed by an in situ generated ammonium (hypo)iodite species. Either H2O2 or tert‐butyl hydroperoxide (TBHP) can be used as an environmentally benign oxidant and a wide range of substrates react to give the corresponding α‐acyloxycarbonyl compounds in good to excellent yields.

  它是碘：分子内和分子间标题反应是由原位生成的亚碘铵（次同）催化的。H 2 O 2或叔丁基氢过氧化物（TBHP）都可以用作环境友好的氧化剂，并且多种底物反应生成相应的α-酰氧基羰基化合物，收率良好至优异。

  A liquid crystal alignment agent allowing formation of an LCD element having good reliability and less residual image, a liquid crystal alignment film, and an LCD element having the liquid crystal alignment film are shown. The liquid crystal alignment agent includes a polymer (A), a photosensitive polysiloxane (B), and a solvent (C). The polymer (A) is obtained by reacting a mixture that includes a tetracarboxylic dianhydride component (a-1) and a diamine component (a-2). The photosensitive polysiloxane (B) is obtained by reacting a polysiloxane (b-1) having an epoxy group with a cinnamic acid derivative (b-2) and an aromatic heterocyclic derivative (b-3) containing nitride, oxide or sulfide.
