摘要

A series of N, N′-linked 1, 2-ethanediyl-poly (benzimidazolin-2-ones) that can be classified as podands, are described. Seven dimers (21–27), three trimers (28–30), a cyclic tetramer (31) and an open-chain benzimidazolin-2-one heptamer (32) have been prepared and characterized by 1H, 13C NMR and by MS. The crystal and molecular structure of the trimer, 1, 3-bis-2-(2-oxobenzimidazol-1-yl) ethyl-2-oxobenzimidazole monohydrate (30) has ...
