Synthetic Route of 14098-44-3, An article , which mentions 14098-44-3, molecular formula is C14H20O5. The compound – Benzo-15-crown-5 played an important role in people’s production and life.
It was shown by means of PMR and IR spectroscopy that benzocrown ethers with sulfonyl-containing exocyclic groups are able to form complexes with alkali-metal cations and also with neutral molecules.The electron-acceptor sulfonyl groups lower the ionophoric activity of benzocrown ethers while retaining cationic selectivity.Sulfonyl containing benzocrown ethers derived from benzo-15-crown-5 form sandwich complexes with potassium ions, which arises from the inversion of the selectivity of ionic transport in favor of potassium.A sulfonyl-containing bridge between the polyether rings in biscrown ethers has a determining influence on the rate and selectivity of the ionic transport.
