THE PREPARATION OF MACROCYCLIC DI- OR TETRAESTER/ETHER COMPOUNDS FROM GLYCOLS WITH DIACID CHLORIDES BY THE USE OF DIBUTYLTIN OXIDE
Several macrocyclic di- or tetraester/ether compounds were readily prepared by reacting various oligoethylene glycols with aliphatic and aromatic diacid chlorides, and hetero atoms-containing diethylene glycols with adipoyl chloride by the use of dibutyltin oxide in good yields.
