Carbon dioxide (CO₂)
is a non-toxic, non-combustible, non-flammable gas. The use of carbon dioxide as a renewable and
environmentally friendly source of carbon in organic synthesis is a highly
attractive approach, but its real world application remains a great challenge.
The major obstacles for commercialization of most current protocols are their
poor catalytic performance and harsh, severe reaction conditions. It is
important to develop new reactions and new protocols for CO₂
transformations at mild conditions and in a cost-efficient manner. This
presentation will discuss new approaches for transforming CO₂ to various
carboxylic acids on terminal alkynes. Various propiolic acids, substituted
acrylic acids and propyl acids have been synthesized with CO₂ in
good to excellent yields under very mild conditions. A transition metal-free
system for the synthesis five- and six-member ring cyclic carbonate will also
be discussed.
