Transition-metal–arene complexes such as bis (benzene)chromium Cr (η 6 -C 6 H 6) 2 are historically important to d -orbital bonding theory and have modern importance in organic synthesis ...

Novel calix[4]arene derivatives 6-8 bearing four phosphonate or phosphine oxide groups at the upper rim and four alkyl ether groups at the lower rim were synthesized from Arbuzov reaction of the ...

These new methods effectively give chemists a unified, practical, late-stage 'molecular editing' toolkit for modifying bicyclic aza-arenes at desired sites in any desired order - greatly expanding ...
