Facial discrimination in monoarylporphyrins: Synthesis and stereochemical behaviour of bis(ligated) monospirobifluorenylporphyrin ruthenium complexes
摘要:
Condensation of dipyrromethane, pyrrole-2-carbaldehyde with either 9,9'-spirobifluorene or fluorene aldehyde yields new meso-monosubstituted, beta-unsubstituted porphyrins. The large size of spirobifluorene hinders the rotation around the C-meso-C(ary)l bond to give, for bis-ligated complexes, two different topological faces. (c) 2007 Elsevier B.V. All rights reserved.
