Synthesis and spectral properties of meso-substituted Ni2+ octaalkylporphyrinates

Recent advances in the synthesis of diazaporphyrins and their chalcogen derivatives

“…Scheme 12 shows the metal insertion reactions of 2,3,7,8,12,13,17,18-octaalkyl-DAP 7H 2 and 10,20-diaryl-DAP 3H 2 , which afforded the corresponding metal complexes 7M and 3M , respectively. The central metals include zinc( ii ), 18 indium( iii ), 22 manganese( ii ), 23 iron( iii ), 24–28 ruthenium( ii ), 29 cobalt( ii ), 30 nickel( ii ), 31 palladium( ii ), 18,31,32 platinum( ii ), 18,31 copper( ii ), 31 and cerium( iii ). 33,34 The peripheral complexation of DAPs with metal salts at the meso -nitrogen atoms is described in section 2.7.…”

Synthesis of Aza-, Oxa-, and Thiaporphyrins and Related Compounds

“…Metal complexes of DAPs other than CuDAPs and NiDAPs have been typically prepared by the reaction of free bases with the corresponding metal salts. For example, indium­(III), iron­(III), − zinc­(II), palladium­(II), , platinum­(II), and sandwich-type cerium­(III) , complexes were prepared according to this kind of metal insertion. Representative examples of the metal complexes of 2,8,12,18-tetrabutyl-3,7,13,17-tetramethyl-DAP 71M and 10,20-dimesityl-DAP 66M , available from 62 and 69 , respectively, are shown in Scheme .…”
