A Novel Synthetic Method for Crown Ethers by a Redox Reaction Utilizing the Intermediate from Diphenyldiazomethane and 2,3-Dichloro-5,6-dicyanobenzoquinone

A synthetic method for the new crown ethers possessing a diphenylmethylene moiety by the reaction of diphenyldiazomethane (DDM) and 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) under the influence of oligoethylene glycols is described.The two types of crown ethers with 1:1 and 2:2 composition of diphenylmethylene/oligoethylene glycol moiety were obtained together with the noncyclic 1:2 compositional diols.The product distributions were dependent on the relative quantities and the manner of addition of the oligoethylene glycols.
