|Title||Cyclic Aryl Ethers, Thioethers and Amines, and method for preparation|
|Abstract||Cyclic aryl ethers, thioethers or amines, and methods for synthesis are disclosed. These cyclic aryl compounds are synthesized by combining a first dinucleophile with a substituted benzene metallized electron-withdrawing complex, having halo or nitro substituent groups, to form a linear bimetallized aryl compound. The linear bimetallized aryl compound is then reacted with a second dinucleophile to form a cyclic bimetallized aryl compound. The metallized electron-withdrawing moieties are then removed from said cyclic bimetallized aryl compound by photolytic demetallation to form a cyclic aryl compound having the formula wherein: X1 and X3 are the same or different and each is a alkyl, heteroalkyl, heterocyclic or aromatic group having up to 6 conjugated rings, optionally substituted; X2 is benzene n1 and n3 are the same or different and each is O, S or N; and n4 is H or lower alkyl.|
