摘要
A new method for the synthesis of maleate(and phthalate)-bridged cyclophanes is described. For example, cyclophanes 4 (or 5) were obtained in 37-55 % yields by treating maleic (or phthalic) anhydride with various benzene dimethanols and reacting the resulting bis-carboxylate salts with various alpha,alpha'-dibromoxylenes. A cyclophane containing copolymer of 4 with 1,3-propanedithiol was prepared. (C) 1998 Elsevier Science Ltd. All rights reserved.
