A new σ-bonded arylcobalt(III) complex

Abstract The reaction of the o -lithio- N,N -dimethylbenzylamine derivative (II) [R H or C(CH 3 ) 3 ] with anhydrous cobalt chloride yielded the complex (III), which contains three carbon cobalt σ_bonds. Evidence for this structure, based on lithium aluminium deuteride reduction of the complex, and on NMR, molecular weight and magnetic susceptibility measurements is presented.

The formation of covalent bonds from transition metals to carbon by direct substitution II. Platinum(II) halides and N,N-dimethyl-2-methylallylamine

Abstract Platinum(II) chloride or lithium chloroplatinate(II) react with N,N-dimethyl-2-methylallylamine to give 2-methyl-3-(dimethylamino)propenylplatinum(II) chloride dimethylamine in 46% yield. Treatment of this compound with either triphenylphosphine or aniline causes elimination of dimethylamine and gives the corresponding triphenylphosphino or anilino complex.
