Reactivity of Dioxoruthenium(VI) Porphyrins toward Amines. Synthesis and Characterization of Bis(arylamine)ruthenium(II), Bis(arylamido)- and Bis(diphenylamido)ruthenium(IV), and Oxo(tert-butylimido)ruthenium(VI) Porphyrins

Abstract

The first isolated bis(arylamine) adducts of a metalloporphyrin undergo oxidative deprotonation to form bis(arylamido)metalloporphyrins (see scheme). Dioxoruthenium(VI) porphyrins are reactive toward trimethylamine giving [RuII(Por)(NMe3)2]. Surprisingly, the reactions between the isolated dioxoruthenium(VI) porphyrins and tert-butylamine are very different from those that employ the dioxo complexes formed in situ. The complex [RuIV(TTP)(NH-p-C6H4Cl)2] represents the first structurally characterized arylamido metalloporphyrin.
