Carboxylation of Organozinc Reagents Using CO₂ in DMF

Significance

This is the first report on the transition-metal-free carboxylation of organozinc compounds. Functionalized alkyl-, alkenyl-, benzylic, and arylzinc compounds prepared by a variety of methods can be involved in this reaction affording good yields of the corresponding acids. This is a simple and useful method for the preparation of functionalized carboxylic acids.
