Tetramethylethylenediamine(dimethyl)nickel(II) is the organonickel complex with the formula (Me2NCH2CH2NMe2)NiMe2 (Me = CH3). This yellow-brown, air-sensitive compound is popular precursor to diverse organonickel complexes. It is prepared from the tmeda adduct of nickel(II) acetylacetonate by reaction with methyl lithium.[1][2]
The tmeda ligand is easily displaced by bases such as bipyridine and diphosphines. Treatment of the complex with electrophilic alkenes results in elimination of ethylene, giving alkene complexes.[2]
