In the same reaction, carboalkoxy-substituted m-phenylene-16-crown-5 is formed. Other mono- and di-functionalized bis(phenylene) crown ethers can be made by one step as well as multistep synthesis from similar starting materials.application/pdfen-USMono- and di(functionally-substituted phenylene) semi-rigid crowns and precursors thereofPatenthttp://pimg-fpiw.uspto.gov/fdd/98/310/053/0.pdf7902185549/349C07D323/00C08G18/3215C08G18/771C08G63/185C08G63/193C08G69/26C08G71/025331098
