1,4,5,8,9,12‐Hexaazatriphenylene (HAT) is one of the smallest polyheterocyclic aromatic building blocks for forming conjugated metal–organic frameworks (cMOFs). However, the strong inter‐molecular steric hindrance impedes the growth of HAT‐based cMOFs. Here we employ on‐surface synthesis to grow single‐layer two‐dimensional cMOFs of M3(HAT)2 (M=Ni, Fe, Co). Using scanning tunnelling microscopy and...
The Michael reaction is a conjugate addition and is one of the most powerful methods with which to prepare functional molecules with a β‐stereogenic center. Despite its success in the formation of various asymmetric carbon–carbon and carbon–heteroatom bonds, enantioselective seleno‐Michael addition remains essentially unexplored. We report here a highly enantioselective Michael addition reaction of...
