Methyl Group Transfer from ZnMe2 to Arsenic(III), an Alternative Pathway to Deprotonation of [CyNHAs(μ-NCy)]2
摘要:
Attempted metalation of the dimer [CyNHAs(mu -NCy)](2) (1) with ZnMe2 gives the novel complex [{MeAs(NHCy)(NCy)}ZnMe](2) (2), a reaction formally involving transfer of a Zn-bonded Me group to the As(III) center, rather than the anticipated deprotonation of the CyNH groups. 2 has an unusual ladder structure in the solid state, composed of a central (ZnMe)(2) dimer unit coordinated by two [MeAs(NHCy)(NCy)](-) anions.
