A variety of alkenylzirconocenes were efficiently carboxylated by CO2 utilizing the (IMes)CuCl catalyst yielding the corresponding α,β-unsaturated carboxylic acids in good yields. This reaction could be carried out in a one-pot operation via sequential carbozirconation of alkynes and carboxylation using CO2 as starting materials under room temperature.
