A facile palladium-catalyzed procedure for meta-selective alkylation of perylenebisimides with alkyl halides has been achieved by direct C−H functionalization.
通过直接的C H官能化,已经实现了一种简便的钯催化的bi双亚胺与烷基卤的亚选择性烷基化的方法。
New liquid crystalline viologens exhibiting electric stimulus-response behavior
Ca. 102∼104-fold increase of electric conductivity progressed autocatalytically with new liquid crystalline viologens, 1–2, when an electric stimulus of 1–30 V was applied.
