Macroheterocycles with an Endocyclic Azo-Group. 1. Tetraazamacrocycles Obtained from Resorcinol

Sultanov, A. V.,Savvin, S. B.

, p. 106 - 109 (1988)

High-dilution azocoupling of bisdiazotized bis-(2-aminophenyl)oligooxa (or thia)alkanes with resorcinol gives tetraazamacrocycles with two endocyclic azogroups.It is shown that azocoupling occurs exclusively at the 2- and 4-positions of the resorcinol ring.
