The reaction of toluene solvated zerovalent nickel atoms with Lappert's and
Weidenbruch's stannylenes :Sn {CH(SiMe3)(2)}(2) and : Sn(C6HBut-2-Me-3-3,4
,5)(2) at - 78 degrees C gave the first homoleptic nickel(hydrocarbyl)stann
ylene complexes of composition [Ni(SnR2)(4)] as stable, red to purple cryst
als in 58 and 33% yield. The parent stannylenes represent ligand systems ca
pable of stabilizing small transition metal centers like Ni-0 without the n
ecessity of any further stabilizing coligands.
