文摘
Nitroxide-induced beta-hydrogen atom abstraction and beta-elimination of rhodium porphyrin alkyls have been observed. Rhodium(II) porphyrin radical were proposed intermediates to form first and subsequently reacted via aliphatic carbon–carbon bond activation with alkyl substituted nitroxides to yield rhodium porphyrin alkyl complexes.
