Adding to the confusion! Synthesis and metalation of pyrazole analogues of the porphyrins.
N-substituted pyrazole dialdehydes are shown to react with a tripyrrane under '3 + 1' conditions to give aza-analogues of the N-confused porphyrins; these novel porphyrinoids show borderline aromatic properties and readily afford organometallic derivatives with Ni(OAc)2 and Pd(OAc)2.
