Cp2TiCl2-catalyzed exchange of alkenes with Grignard reagents and subsequent reaction with CO2 provides carboxylic acids in high yields. The reaction proceeds with a wide range of alkenes under mild conditions. Styrenes can be transformed to α-aryl carboxylic acids, and aliphatic alkenes give linear alkanoic acids.
