<p>NEW MATERIAL:A complex of formula I (n is an integer 1-20; m is an integer 1-6; l is an integer 1-6; X is halogen). USE:An oxygen adsorbent. PREPARATION:A carboxylic acid of formula II is reacted with 5,10,15,20-tetra (alpha,alpha,alpha,alpha-o-aminophenyl)porphyrin of formula III in the presence of a base to form a compound, which is then reacted with anhydrous aluminum chloride in the presence of anisole to remove the benzyl group thereform. The resultant compound is further reacted with ferrous bromide in the presence of pyridine and then treated with 48% hydrobromic acid, concentrated hydrochloric acid, etc. to give an intermediate in which bromine ions, chloride ions or iodine ions are coordinated. The intermediate is then reacted with an alpha,omega-dicarboxylic acid anhydride, etc. of formula IV in the presence of a basic catalyst and then with one terminal aminooligoethylene glycol of formula V to afford the aimed complex of formula I .</p> |
