Zinc reagent
Zinc reagent
Organozinc compounds are a class of organometallic compounds which contain a carbon-zinc bond. In contrast to C-Mg and C-Li bonds, the C-Zn bond is highly covalent, and hence organozinc reagents are less reactive than the analogous organometallic reagents, such as Grignard and organolithium reagents. Organozinc compounds are usually volatile, pyrophoric and sensitive to oxidation. These compounds are classified on the basis of the number of the carbon atoms directly bound to the zinc atom. The three major classes of organozinc compounds are:
ionic zinc compounds, otherwise called organozincates
diorgano zinc compounds
heteroleptic RZnX compounds in which X is an electronegative substituent, often a halogen atom
