Abstract
The reactions of 2-formyl-5,10,15-20-tetraphenylporphyrin (Ia) with nitromethane and of its Cu complex (Ib) with nitromethane, malonic acid, and its esters have been investigated. On interacting porphyrins (Ia,b) with nitromethane in AcOH/BuNH2 the 2-(2-nitrovinyl)porphyrins (IIa,b) were formed, in liquid NH3 the nitroalcohols (IIIa,b) were formed, and in DMF/BuNH2 the dinitro derivatives (IVa,b) were formed. The interaction of porphyrin (Ib) with malonic acid and its esters led to the corresponding condensation products in high yield.
