Descriptions
The compounds 2,2'-dihydroxy diphenyl ethers [2] were sythesized from diphenyl ether as starting material via four steps. Several new crown ethers including diphenyl ether moiety [4] were obtained from the reactions of [2] with polyethylene glycol ditosylates [3] by use of alumina support coated with potassium fluoride (KF-support). Particularly, the solution of 2,3-5,6-dibenzo-18-crown-6 [4d-1] and potassium permanganate in nitrobenzene formed a complex which incorporated K^+.
