Binaphthyl metallomacrocycles for complexation of neutral molecules
Reichwein, Arjen M.,Verboom, Willem,Reinhoudt, David N.
, p. 358 - 366 (1993)
Binaphthyl salophen crown ethers 1 and 2, containing an immobilized electrophilic uranyl cation, were synthesized by cyclization of dialdehyde 10 with 1,2-benzenediamine (14) or cis-1,2-cyclohexanediamine (15), respectively, in the presence of Ba(2+) as a
