The challenge of converting carbon dioxide, a renewable carbon feedstock, into value-added organic products remains highly inspiring for organic chemists. Although extremely challenging, now the carboxylation of aryl and vinyl chlorides has been realized under ambient conditions with a simple and accessible NiII complex. This attractive protocol demonstrates the unique potential of transition metal chemistry in CO2 fixation catalysis.
