Abstract
Reaction of Ru (4-Cl-TPP) (CO) (MeOH) [4-Cl-TPP = meso-kis (4-chlorophenyl) porphyrinato dianion] with 3-chloroperoxybenzoic acid (m-CPBA) followed by treatment of the mixture with an aqueous ammonia solution afforded the first nitrido ruthenium porphyrin Ru(4-Cl-TPP) (N) (OH). Three new nitrido osmium (VI) porphyrins, Os (Por) (N) (OH) (Por=TPP, TTP, and 4-Cl-TPP), were synthesized from oxidation of Os(Por)(NH3)2 withm-CPBA. All these new complexes were characterized by1H NMR, IR, UV/Visible spectra and elemental analyses. Both nitrido ruthenium (VI) and osmium (VI) porphyrins are diamagnetic. Their pyrrole proton resonances appear at slightly lower fields than those of the corresponding dioxo Ru(VI) and Os(VI) porphyrins. The {ie89-1}, or {ie89-2}, region is obscured by the strong “oxidation state marker” band.
