Abstract
Evidence from visible and n.m.r. spectra for the acidity of the C-10 protons in 1,19-dideoxybiladienes-ac is presented. The cyclisation of the 1,19-diunsubstituted 1,19-dieoxybiladienes-ac free bases to corroles is shown to proceed by a free-radical mechanism, and to differ from the mechanism of cyclisation of the corresponding metal complexes.Keywords
