A new ferrocene–anthracene dyad anion receptor 1 bearing amide and 1,2,3-triazolium donor groups has been designed and synthesized. In CH 3 CN solvent, 1 shows a dual-signaling sensing toward H2PO4- over other anions, with its fluorescence a large enhancement, and electrochemical potential a negative shift.
An efficient procedure for asymmetric Michael addition reaction of cyclic ketones with low activated chalcones catalyzed by pyrrolidine-based phthalimide and 1,8-Naphthalimide catalysts was developed. The corresponding products were obtained in high yields with high diastereoselectivities (up to 99:1 dr) and high enantioselectivities (up to 96% ee) under mild conditions.
