EPSRC : Thomas Kieran Redpath : EP/W522260/1Catalysis is an essential way to speed up chemical reactions and to decrease the energy demands of those reactions (e.g. by decreasing reaction temperatures). Most homogenous catalysis, where the starting materials and catalyst are in the solution phase together, in the pharmaceutical and agrochemical industries requires expensive, rare, and often toxic heavy transition metals such as palladium, platinum, iridium, and rhodium.Nickel is a cheap and abundant metal that can be used to achieve many of the same reactions that palladium and platinum can perform, allowing for more complex materials to be made with greater ease, at lower cost, and more sustainably. Currently, palladium (considered a rare and precious metal) is used to do this in molecules where the desired outcome is the coupling of carbon and phosphorous to form a new bond. Due to the similar reactivity of nickel and palladium in some circumstances, this is something that should be possible with nickel, but for which there are relatively few known examples. The aim of the project is to develop nickel-catalysed reactions that form bonds between carbon and phosphorus, using catalysts with nickel at the centre. The use of ligands, which are groups that attach to the metal catalyst, changes the properties and reactivity of the catalyst; our partners at Dalhousie University (Nova Scotia, Canada) are world experts in ligand design and development and will share their expertise to make our aims a reality. This will enable more cost-effective catalysis in the future for these kinds of chemical transformations.

EPSRC：Thomas Kieran Redpath：EP/W522260/1催化是加快化学反应并减少这些反应的能量需求（例如，通过降低反应温度）的重要方法。 Most homogenous catalysis, where the starting materials and catalyst are in the solution phase together, in the pharmaceutical and agrochemical industries requires expensive, rare, and often toxic heavy transition metals such as palladium, platinum, iridium, and rhodium.Nickel is a cheap and abundant metal that can be used to achieve many of the same reactions that palladium and platinum can perform, allowing for more complex materials to be made with greater放松，以较低的成本，更可持续。当前，钯（被认为是一种稀有金属）用于在所需结果的分子中进行此操作，其中所需的结果是碳和磷的偶联以形成新的键。由于在某些情况下镍和钯的反应性相似，因此镍应该是可能的，但是对于该镍来说，相对较少的例子。该项目的目的是开发使用镍和磷之间形成键的镍催化反应，并使用中心的镍催化剂。使用配体的使用是附着在金属催化剂上的基团，会改变催化剂的特性和反应性。我们在达尔豪西大学（加拿大新斯科舍省）的合作伙伴是配体设计和开发领域的世界专家，并将分享他们的专业知识，以使我们的目标成为现实。这将使未来的这种化学转化将来更具成本效益的催化。
