Alkylcobalt(III) compounds with ammine ligands

Synthesis of C-8 alkyl xanthines by pentaamminecobalt(III) complex

“…The amminecobalt(III)-promoted aerial oxidation of alkyl hydrazines afforded alkyl radicals, and some primary alkyl radicals were trapped by pentaamminecobalt(III) to form alkyl cobalt(III) cations [15]. However, these compounds are labile and decomposed to return alkyl radicals.…”

Iron, cobalt and nickel

“…9 Cobalt pentaammines [Co(NH 3 ) 5 R] 21 (R ¼ Et, Pr n , Bu n , C 6 H 5 CH 2 CH 2 , 3-NH 2 Pr) have been synthesised. 10 Complexes of the versatile terpy and its derivatives continue to interest. An iron(II) complex with a terpyridine type ligand exhibits liquid crystal behaviour.…”
