preparation of meso tetraphenylchlorophinato nickel ii by stepwise deformylation of meso tetraphenyl 2 3 diformyl secochlorinato nickel ii conformational consequences of breaking the structural integrity of nickel porphyrins
Inorganica Chimica Acta, 2005Co-Authors: Christian Bruckner, Michael A Hyland, Ethan Sternberg, Jill K Macalpine, Steven J Rettig, Brian O Patrick, David DolphinAbstract:The stepwise, Wilkinsons Catalyst induced decarbonylation of (meso tetraphenyl 2,3 diformylsecochlorinato)Ni(II) (4) to pro duce the monoformylated pigment (meso tetraphenyl 2 formylsecochlorinato) (5) and (meso tetraphenylchlorophinato)Ni(II) (6) is described. Thus, we have shown how to degrade one pyrrolic unit of the starting material, (meso tetraphenylporphyrinato)Ni(II) (2) in three steps to an aldimine linkage. The conformational changes of the porphyrinic macrocycle during the course of this deg radation, as determined by comparison of the X ray crystal structures of the compounds, are discussed. A comparative study delin eates the UV Vis spectroscopical consequences. In addition, the chemical reactivity of (meso tetraphenylchlorophinato)Ni(II) (6) suggests the existence of an azepine derived pyrrole modified porphyrins (11, 12). � 2004 Elsevier B.V.
