Abstract:
Essentially all metals and metalloids can be coordinated to porphines, but unlike the phthalocyanins, where a template reaction can frequently be employed to give the metallo complex, preformed macrocyclic porphines themselves must be metalated. Adler et al. have recently described a method that is general for the preparation of many metalloporphines; there are, however, some systems that can neither be metalated using dimethylformamide, or other high boiling basic solvents, nor give quantitative metalation and so require special purification procedures. Complexes in this category are the nickel and vanadyl derivatives of 5,10,15,20-tetraphenyl-21H,23H-porphine (meso-tetraphenylporphyrin, H2tpp) and magnesium complexes, in which case other methods for metalation must be employed. THE FOLLOWING PROCEDURES WERE REPORTED:- A. [5,10,15,20-tetraphenyl-21H,23H-porphinato(2)]-nickel(II) B. Oxo[5,10,15,20-tetraphenyl-21H,23H-porphinato(2-)]-vanadium (iv) C. [2,3,7,8,12,13,17,18-Octaethyl-21H,23H-porphinato(2-)] -magnesium(II)
