Heteroleptic metallacyclic potassium organodiamido zincate complex. Synthesis and structure of polymeric {[K(thf)][MeZn(ButNCHCHNBut)]}n

Abstract

The reaction of the C–C coupled dimer of two neutral organozinc radicals, [MeZn(Bu^tNCHCH(NBu^t)CH(NBu^t)CHNBu^t)ZnMe]1, with potassium in tetrahydrofuran affords the metallacyclic neteroleptic potassium organodiamido zincate K[MeZn(Bu^tNCHCHNBu^t)]2 quantitatively, which exists in the solid state (X-ray crystallography) as a linear polymer formed by alternating potassium cations and organodiamidozincate anions.
