Application of CO2 as a renewable feedstock and C1 building block for prodn. of commodity and fine chems. is a highly challenging but obvious industry-relevant task. Of particular interest is the catalytic coupling of CO2 with inexpensive unsatd. hydrocarbons (olefins, dienes, styrenes, alkynes), providing direct access to carboxylic acids and their derivs. Although not brand new for the scientific community, it is still a complete challenge, as no truly effective catalytic system has been reported to date. In this Perspective, we discuss the available exptl., theor. and mechanistic data for such homogeneously catalyzed carboxylation processes. A special focus is placed on the understanding of the key elementary steps and of some thermodn. and kinetic constraints.
