Carbon dioxide (CO2) is all around us, representing a grave environmental threat. It also represents an opportunity- if we can turn it into useful molecules like plastics or pharmaceuticals, we could fight its environmental threat and use its wide availability to our advantage. Some chemists have managed to use CO2 to add carbon atoms to nitrogen. Carbon-nitrogen bonds are incredibly common in life, so this is a triumph. Nitrogen is above phosphorus in the periodic table, this means they act similarly, and phosphorus-carbon bonds are present in life, but more importantly, really useful for making new molecules. For example, phosphorus-carbon bond chemistry in the form of the "Wittig Reaction", and catalysis relying on ligands with phosphorus carbon bonds are used to make all sorts of useful compounds.Despite all of the potential offered by phosphorus-carbon bonds, and its similarities to nitrogen, no one has yet reported a catalytic method to make carbon-phosphorus bonds from CO2. We think that we will be able to do this. In our group we investigate the possibility of copper as a catalyst, which is as inexpensive as the pennies in your pocket. A catalyst is a compound that is added in small amounts that makes a reaction go faster. We have previously shown that copper can catalyse the formation of phosphorus-carbon bonds from a molecule that is very similar to CO2. We want to investigate how we can extend this to carbon dioxide, and to expand it to transform the carbon oxygen bond into carbon hydrogen bonds, which are more useful for chemistry.

二氧化碳（CO2）就在我们身边，是一种严重的环境威胁。它也代表了一个机会-如果我们能把它变成有用的分子，如塑料或药物，我们可以对抗它的环境威胁，并利用它的广泛可用性为我们的优势。一些化学家已经设法用二氧化碳把碳原子加到氮上。碳氮键在生命中非常普遍，所以这是一个胜利。氮在元素周期表中位于磷之上，这意味着它们的作用相似，磷-碳键存在于生命中，但更重要的是，它对制造新分子非常有用。例如，磷-碳键化学中的“维蒂希反应”，以及依赖于含磷碳键的配体的催化作用被用于制造各种有用的化合物。尽管磷-碳键提供了所有的潜力，并且它与氮相似，但还没有人报道过从CO2制造碳-磷键的催化方法。我们认为我们将能够做到这一点。在我们的小组中，我们研究了铜作为催化剂的可能性，它就像你口袋里的硬币一样便宜。催化剂是一种化合物，加入少量，使反应进行得更快。我们之前已经证明，铜可以催化一种与二氧化碳非常相似的分子形成磷-碳键。我们想研究如何将其扩展到二氧化碳，并将其扩展到将碳氧键转化为碳氢键，这对化学更有用。
