Abstract

The diamine-dialdehyde condensation of biphenyl-2,6,2',6'-tetracarbaldehyde (6) and 2,2'-diaminobiphenyl (3) in benzene (TsOH catalyst) gave the tetra Schiff base 9,15,24,30-tetraazahexabenzo[d,f,jk,o,q,uv] dodecalene (4). 10,14,25,29-Tetraaza[d,f,jk,o,q,uv]dodecalene (5) was prepared analogously from 2,6,2',6,-tetraaminobiphenyl (7) and biphenyl-2,2'-dicarbaldehyde (2). The condensation of 6 with o-phenylenediamine and with 2,3-diaminonaphthalene afforded “hydride shift” products 10 and 13. The geometries of 4 and 5 are briefly discussed.
