Ether-linked phenyl ring

The thyroxine analogue 3,5-di-iodo-L-thyronine (18) contains two ether-linked benzene rings. The two phenyl rings are nearly mutually perpendicular. [Pg.240]

The polymers under study have a chemical repeat comprised of three phenyl rings linked by azomethine groups forming the rigid unit and a flexible polymethylene spacer (1 to 16 methylene units) linked to the rigid units by ether oxygens. [Pg.257]

Presumably the linking group is >NCH—N<. Bisamides of l-(amino-phenyl)-2-pyrazolin-5-ones and of 3-amino-2-pyrazolin-5-ones have been used. l-(3-Aminophenyl)-3-methyl-2-pyrazolin-5-one reacts with many aldehydes and ketones to form polymers.964 Probably condensation occurs at C-4 and the amino group. The product of reaction of p-cresol with formaldehyde has been found to react with 1-(4-hydroxy -phenyl)-3-methyl-2-pyTazolin-5-one to give a polymer that must have the aromatic and pyrazolinone rings connected by ether linkages.1269... [Pg.127]
