Notes:
Cyclic oligomers of butylene terephthalate (16a - d) were synthesized by cyclocondensations of the corresponding dicarboxylic acid dichlorides (2 or 13) with diols (4, 10, or 15). The linear educts 2, 4, 10, 13, and 15 were obtained by stepwise synthesis. The resulting cyclic esters 16a - d were characterized by IR, NMR, and mass spectroscopy.
