Abstract
A novel zerovalent zinc species and an organozinc reagent are disclosed. The zerovalent zinc species is directly produced by reaction of a reducing agent on a zinc salt, preferably Zn(CN).sub.2. The organozinc reagent results from the reaction of the zerovalent zinc species and an organic compound having one or more stable anionic leaving groups. These organozinc reagents include a wide spectrum of functional groups in the organic radical, and are useful in a variety of reactions schemes.
Claims23
A zerovalent zinc species comprising a mixture of formally zerovalent zinc metal atoms and an alkali metal salt of cyanide.
A method for preparation of a zerovalent zinc species comprising contacting a Zn(CN).sub.2 species in a nonhydroxylic solvent with a reducing agent having a reduction potential of about -1.0 volt or more negative relative to a standard calomel electrode.
A zerovalent zinc species comprising a mixture of formally zerovalent zinc metal atoms and an alkali metal salt, wherein the alkali metal salt includes an anion selected from the group consisting of cyanide, nitrate, nitrite, and combinations thereof.
A method for preparation of a zerovalent zinc species comprising contacting a Zn(II) salt in a nonhydroxylic solvent with a reducing agent having a reduction potential of about -1.0 volt or more negative relative to a standard calomel electrode, wherein the Zn(II) salt includes an anion selected from the group consisting of cyanide, nitrate, nitrite, and combinations thereof.
