Ring substituted crown ethers and method of producing same |
| abstract |
There is provided a new class of crown ethers characterized by an --OH functional group attached to a carbon atom in the heterocyclic ether ring portion and derivatives thereof. A novel process for making such crown ethers is also provided which is characterized by reacting a bisphenol ether with an epihalohydrin to effect ring closure and provide the appendant --OH group. n These products are especially useful as complexing agents. |
